Calculator Mk.3

[icy mauve]

its in some old persons attic collecting dust

i spent a minute searching and i couldnt find anything

im convinced they dont exist

[viral token]

for bigger number the design is not as simple

since i do want it to be able to do 99999999999999+99999999999999 ill make the full machine

its gonna look very fun lol

cascading numbers

cause i do need to add a shifter to every digit

[icy mauve]

u also need zero detection

but thats another story

[viral token]

yeah thats just for the display

its a not gate

[icy mauve]

can i join ur game, i am very interested 💯

[viral token]

if it goes to 10 the 0 get displayed and the 1 gets shifted

[viral token]

sure do you have a priv?

[icy mauve]

ofc i do

[viral token]

add Adrie734

[icy mauve]

yee

[viral token]

the design is gonna work well for addition and substraction

gonna be a bit weird for multiplication

and divison should be fine

[icy mauve]

division is a pain

did u get my epic request

[viral token]

yes

can't see your server in the list tho

[viral token]

uh

maybe i have too many server on my server list

hold on let me block some random guy

[icy mauve]

i got like 4 i havnt paid for

[viral token]

can you try again?

[icy mauve]

its still being annoying

shood i jus dm u the link

[viral token]

can you just trun on friend allowed?

oh yeah that works too

[icy mauve]

friends are allowed

did u accept the freind request im so confused???

[viral token]

i did

[icy mauve]

lemme reload roblos

im just give u link, roblos is being annoyin

[fluid sluice]

4rd?

[icy mauve]

it was originally 3rd but i made a mistake, and 4rd is wayyy funnier than 4th

[fluid sluice]

True

[icy mauve]

yeeee

[viral token]

[short sphinx]

Yeah imma use the other design as it is 3 tick faster and just seems less janky

I really need it to be reliable

[icy mauve]

5th layer built, gotta spend an hour wiring it tho

[edgy jacinth]

This remind me about windows xp loading time 😆

[icy mauve]

im just as slow if not slower (im wayyy slower)

[edgy jacinth]

[icy mauve]

5TH layer is wired for the most part, just got the finicky bits left which im not looking forward too so thats tmr's problem

[icy mauve]

idk y i thought the finicky bits would take forever, took me 15 minutes

[viral token]

[icy mauve]

i mean, if i messs up 1 wire then it wont work at all

[viral token]

so it is done?

[icy mauve]

no lol

i need 33 bits on both sides, ive dont the x axis ez pz

dat was only 3 layers

[viral token]

so you did half?

[icy mauve]

nope

[viral token]

what's left?

[icy mauve]

i need 33 bits on the y-axis

i have technically done 16

[viral token]

ah ok

[icy mauve]

but i havnt finished that layers x-axis

[viral token]

when you're done you should try square roots

its only 3 calculation

you should be able to run it

[icy mauve]

i think i will

[viral token]

or 1 if you do exponents

[icy mauve]

i dont think itll require any additional space as all i would have to do is route a few wires

[viral token]

yeah just make 2 registers

even one is enough i think

[icy mauve]

i do wanna get the bcd done first

because thats gunna take a lot of space

[viral token]

use bit out frfr

[icy mauve]

that would go against the entire point of the project lolol

[viral token]

aw

[icy mauve]

also i need 16 layers

im on the 6th 😭

i think chatgpt was right abt this taking me 3 weeks

[viral token]

chatgpt is a big liar

don't trust him

like sometimes he says "yeah 1+1 = 2"

you tell him "i dont think so"

and he can't disagrre so he says "yeah 1+1=3 you're right!"

[icy mauve]

i mean, it is a chat bot

a dumb one at that

[viral token]

he'd rather come up with made up math formula that don't do crap than disagree with you

[icy mauve]

it doesnt want to hurt anyones feelings 🔥

who is afraid to be told their wrong by a chatbot, i just want my damn fromula

if i got it wrong TELL ME

[viral token]

like when i asked about pathfinding he literaly invented math

[icy mauve]

💀

[icy mauve]

ik at this point all the pictures look the same, but trust me when i say theres another fully wired layer on there

every 3 layers i gotta wire up the multiplexers, itll take me like 15 - 20 mins but that can wait

[icy mauve]

since im worried abt base size and the increasing size of the divider, imma ditch it for now and make work on the B.C.D.

if terms do come to worse, i have a 'working' divider that is big enough for 16-bit calculations

[icy mauve]

BCD coming along nicely, i will have to stack it awkwardly unfortunately

right to left, left to right

there is enough space, itll just look a bit weird

[edgy jacinth]

Another way to convert using bit i/o
Ex : decimal 52 = Binary 110100

[icy mauve]

gotta do some crazy stacking

its only gunna get worse

[short sphinx]

Server killer

[icy mauve]

nahhh, its only 67mb

[icy mauve]

getting increasingly worse to wire

currently its at 16-bit, so i gotta double it

actually triple it cuz its a triangle

[short sphinx]

Make a big cube under si the floor is at a way higher level

[icy mauve]

idk wat u mean, but its only finna get higher

[viral token]

just raise the floor pretty much

so it gets way easier to build

[icy mauve]

i mean, i could

idk why im tryna make an excuse, sure ill make a platform

tmr tho, i did my daily session

[viral token]

https://tenor.com/view/goo-goo-ga-ga-baby-dont-hurt-me-mike-o'hearn-non-chalant-gif-12366016126451834445

[icy mauve]

hour and a half

wayyyyy to long

[fluid sluice]

So... much... B L U E

[icy mauve]

MORE BLUEEEE

[viral token]

straighten your wires 😭 🥀

[icy mauve]

the wires are straight no?

[viral token]

i meant like

only 90°

[icy mauve]

its harder to do that whilst its floating lol

[viral token]

fair

[icy mauve]

this last me like 2 hours tmr

keeping up that 200k+ average at the logic shop

[viral token]

can i arrive at a certain velocity into that pile proving some law of thermodynamics?

[icy mauve]

idk, u might end up going straight through the gap

[icy mauve]

mmmm, 4th layerrrr

thing is, its sort of exponential of how long its gunna take,
the bigger it gets the less i get built in the same amount of time

[icy mauve]

i mean, this is 20-bit bcd, i need to add an extra 13 bits, which is 112 more sections

and at my current rate of 12 sections a day, itll take me 9 days😭

im defo finna hit 100umb

hopefully the game holds up

im currently at 76umb, things aint lookin good lol

keep in mind i gotta finish the second half of the divider aswell

and all the loopers, small bus line and the bidmas circuit, im defo reaching 130+umb

[fluid sluice]

Time to rebuild it all, but make it more optimized

[icy mauve]

sadly it is fully optimised 😭

is just ive come to learn binary is useless in this game

[icy mauve]

counted it all up, i have exactly 13,333 components placed, which is pretty fun

[icy mauve]

running out of room on the left side, gotta shift it to the right more than u expect

the last few rows will be 10 sections long, its currently ay 7 so im almost there

3 rows of 8 and 9 then 4 rows of 10, 91 more sections to go

[viral token]

up

🥶

[icy mauve]

dis is wat i meant abt the shift

its moved over 10 times, cuz theres only 10 more rows i gotta build

[icy mauve]

bcd the longgg way

[low vale]

This will be the longest tutorial in roblox youtuber history

[viral token]

"Ok so first of all you place this gate right there then this gate right there"

x 13 000

[icy mauve]

ive recorded the entire process, it is technically a tutorial lol

[low vale]

Ah nice

[viral token]

make a timelapse

[icy mauve]

ikr lol

[icy mauve]

smartttt

how do compress 80 hours of footage?

[viral token]

painfully

[low vale]

Really quick too. Youtube has slowdown features

[viral token]

worst ive done is like 3 hours so idk

where the heck do you even store 80 hours worth of footage

[icy mauve]

youtube...

[viral token]

bruh

[icy mauve]

i stream it, then export it

ez pz

[viral token]

its like 300 gigs

[icy mauve]

💀

[low vale]

DAIM

[viral token]

compress all your vid one by one ig

[icy mauve]

ill just let you do it for me lol

[viral token]

pluh

[low vale]

💀

[viral token]

if you pay me

wait nvm thats prob considered crosstrading lol

[low vale]

Wait i cant delete it

[icy mauve]

nah, ill be 'hiring' your skillz

[icy mauve]

5 pounds?

[low vale]

$50

[icy mauve]

damn

[low vale]

Jk

I suck

[viral token]

i guess if nothing is in oakland it works

[icy mauve]

ill send you all 36 videos right now

[low vale]

Me?

Nah

[icy mauve]

unless you wanna compess it lol

[low vale]

All i have is a phone that has internet access

[icy mauve]

oof

[low vale]

Oof indeed

But still i need to build this but more compacted

My base is in layers

[icy mauve]

jus use the calculator component lol

[low vale]

Bedrock is logic “brains” layer

Nah

I wanna switch modes with a button

Wait can an interacter do that?

[icy mauve]

idk, never used it

[low vale]

Ah ok

Maybe layer -7 will be the lab for research

[viral token]

use the calculator gate lol

all this fits with like 5 gates

[low vale]

Interactor use it?

[viral token]

you can change the mode with an interactor yeah

[low vale]

:0

I did not know that

Ty!!!!!!!

[viral token]

to display stuff you'ill need num splitters

[low vale]

Ik that

[viral token]

nice

[icy mauve]

3 rows of 9 and 4 rows of 10 left to build

then the decoders start appearing, yipee

[low vale]

Not gates instead of switches will be a great option

[icy mauve]

the switches are only there for testing, the wires will jus connect into the tethers

6th layer has begun, 2 more rows of 9

[low vale]

Nice

[icy mauve]

it takes so long to wire each section lol

a row of 9 took me 30 minutes

[low vale]

Wow

[icy mauve]

and theres prolly over 100 by now

im still gunna blame the multiplier

[icy mauve]

4 rows of 10 left and BCD is finished

love this plot tho, my base doesnt deload anymore

saves me so much time

lol

[icy mauve]

gotta wire that last row, then theres only 2 rows left

almost done : )

hopefully this will be enough to finish it

i doubt that tho

[icy mauve]

1 more row, then i gotta build the decoders

[icy mauve]

it is done

🔥 🔥 🔥

now to split the tether into many groups of 4 from left to right (picture pov), then its decoders

imma work on the decoders first tho, should be simple

i could compact it, but it fits within the 4 tether spacing so it wont matter that much

[icy mauve]

also i just counted up the tethers, theres 43, so ive made it too big...

to fix it, nothing really changes since u build it from big number to small (simple terms)

so i just make a 'new' 1 line

so its now a 34-bit B.C.D. instead of 33

which is better lol

oh, i also forgot 1 wire in EVERY section, so i gotta do that aswell

idk how i made it this far without noticing lol

[fluid sluice]

Whole ocean of wires

[icy mauve]

theres always room for more blueeee

there will be 11 decoders

so thats an 11 digit number so itll be in the billions

a lil bit bigger than my previous calculator which could only display 65536

i can input double that on this one

still going strong

[viral token]

tps?

[icy mauve]

still in the 50's

freezes are getting more common tho

[viral token]

run it

and look at tps

[icy mauve]

ill have to rejoin, gimme a sec

i can only run the bcd by itself atm, cuz nothings connected to it just yet

but theres still a LOT of connections

[icy mauve]

💀

slowed the game down LOL

[viral token]

what tps

[icy mauve]

just counted up slowly tbh

got stuck at 12 for a second

[viral token]

yeah so ded server

as long as it doesnt crash

[icy mauve]

itll be fineee

might take a minute to get a big answer tho

lez gooo, 2tps

[viral token]

https://cdn.discordapp.com/attachments/1194235723683999757/1330815884247175189/togif.gif

[icy mauve]

keep in mind, this is only the bcd,

its gunna get worse

the divider mixed with the bcd, 2 slow things together is gunna KILL the server

[icy mauve]

the decoders are finished

and that means, the B.C.D. is finally 100% complete

just gotta connect the output to the screen and the decimal to binary converter

not as simple as just connecting it, i might need another converter because each tether does 1 line on the screen

in simple terms i need to convert the 7 tethers into 10...

sorta like converting 7 segment into decimal

got zero idea on how to do it, but im sure ill think of something

[viral token]

why take the output from the 7 seg?

if you already have the binary output before hand

[icy mauve]

its a different form of binary

bcd converts sayy,,, 7834 into 7, 8, 3, 4. but in binary

[viral token]

no but like

why do you need to do it the other way now

[icy mauve]

why i need it in decimal?

[viral token]

decimal to binary

why do you need that

[icy mauve]

damn, i dont lol

maybe i do, not sure

[icy mauve]

ohh was u on abt this

cuz the calculator is in binary, but the input is in decimal, so i need a decimal to bianry converter

it was one of the first things i built

[viral token]

the humble bit in and bit out gate

[icy mauve]

nahhh, doesnt exist

[icy mauve]

took me 2 hours, but i got 1, 7-seg to decimal done

10 more to go, das tmr problem tho

if u wanna know why it took so long, dis is why

had to re-wire it twice, nothing was wrong with it, i just had to move it

specifcally half a stud...

[icy mauve]

uhoh... first crash in private sever....

almost done, ill finish it tmr cuz i dont wanna crash again lol

[icy mauve]

another crash......

[icy mauve]

everything is finished, all thats left is to connect everything

i will have to make a few changes to my original ideas, since crashes are beginning to happen, i dont want to push my luck any further

the divider most likely will stay as it is tbh, to get it to 33by 33 bit will add an extra 19umb

i do still want to try and add the loopers, hopefully i can find a way to compact down the size

also whilst i was writing that, my server crashed again...

[icy mauve]

its a very sad day today, the server crashed 4 times in less than an hour

i really am pushing my luck, im so close to being done aswell.

based on the new rate of 1 crash per 15 mins, i doubt i can build the loopers

all i did, was place 110 tethers, and connect 150 wires

i think i just gotta push through the crashes and do what i can because this is very disappointing

[icy mauve]

did what i could

[viral token]

does the server crash or your client

[icy mauve]

server

[viral token]

in privates?

[icy mauve]

yes

[viral token]

yeah you're cooked

while running it?

[icy mauve]

nah

[viral token]

ok you're extra cooked

[icy mauve]

havnt got to that bit yet

[icy mauve]

when i run the bcd, i go from 50ping to 180 and it puts hella strain on the server 💀

[icy mauve]

I love this game.....

not even 20 mins and the server crashed twice

all i wanna do is add zero detection

[icy mauve]

done the zero detection, and as always, one fix creates another problem

zero detection was as easy as 2 rows of and gates

[icy mauve]

am still a bit timid to connect the tethers to the screen as i would much rather prefer blockers to prevent this issue, but atm i am hella poor

i think to connect everything together ill need around 90k, but if i wanna try and add the loopers ill need 300k

also, fyi I think im up to around 12 private server crashes, cannot be good I am cooked.

[young vigil]

😂

[icy mauve]

😔

[icy mauve]

managed to gain enuf money to replace the tethers with blockers

should be able to connect them all within 2 - 3 server crashes

i will need to think of how im gunna detect once the numbers have become stable to let them through

a few AND gates should to the trick

[icy mauve]

was making some good progress, 2 crashes in, should be done within 1 more

[young vigil]

What progress its ?

[icy mauve]

only like 250 more wires

i could do thousands but the game cant handle my base anymore

[young vigil]

250 wire bcd ?

[icy mauve]

bcd is finished, im just connecting it to the screen

[young vigil]

Ahh

How much wire conect to a 14 segmegment there?

[icy mauve]

i think just below 100 wires for each one

theres 20 screens so just under 2000

[young vigil]

So this guy handle about 100 wire?

[icy mauve]

around that yea, but only 7 actually have power at once

low as 2, high as 7

its a very robust set up tbh

i could scale it down a bunch, but it would end up being the same size pretty much

[young vigil]

Another 250 more wires and calculator mk.2 is finish?

[icy mauve]

nahh

[icy mauve]

thought u meant what progress i had made sry

not what i had left

[young vigil]

Yes its

[young vigil]

This another qs

[icy mauve]

i think its more in the line of 2000 wires approximately

i still have a LOT more connections to do, not much building just connecting

[young vigil]

Dang this sad

[icy mauve]

it really is tbf

other people have wayy bigger bases and can still play in public servers, im at 107umb and crash private servers

[young vigil]

And u have tons of signal that run at ur base realtime

[icy mauve]

theyre all idle

except for the tps meter, shouldnt make a difference

[young vigil]

Huh , i wish u can complete ur project

[icy mauve]

thank you

[icy mauve]

the only thing left to do with this lil bit is to have some stable detection

which is surprisingly really hard

i think the simplest solution would be to find a wire in the bcd that constantly changes untill the answer is ready (stable) and use that, but there isnt really 1 specific wire that keeps on changing

[viral token]

make another calculator delay it by a few ticks and compare both output

[icy mauve]

i could string a few together but i would need to string all of them together

[icy mauve]

i could use delays

but im a bit poor atm and i cannot get any money

im being skint basically

[icy mauve]

might give this a go but idk how it would work, becuase as soon as 1 turns on, itll stay on?? so the blockers will just let it through

[viral token]

can't you just take the output right before the display?

so you only have like 20 wires

[icy mauve]

wym, expound

[viral token]

take final output every few seconds you put it in memory and if it matches with the previous check then its done

[icy mauve]

alr, lemme try an break it down, so ur saying i let an input through, wait a sec, if its different it aint done?

[viral token]

if the result is different than what it was a few sec ago then its not done

[icy mauve]

right, but which wire do i use for the input, cuz if i group a few together with NOT gates itll just be on all the time, and if i used tethers ill get higher signals

tethers might work tbh.

[viral token]

the ones that are meant for the display

but you only display it when its done

[icy mauve]

but i gotta group them up

[viral token]

whats the issue?

[icy mauve]

if i just choose 1 wire, theres a chance that wire wont change

so i gotta group all of them up

[viral token]

yeah

do that

wire stack

[icy mauve]

alr lemme make a... ✨prototype✨

game crashed before i could add anything else

should work right, just gotta add a clock to switch blockers

and find a way to clear the memory cells

got no idea on how to make a clock tho

[viral token]

tether clock so you dont use any other gates 😄

[icy mauve]

how many tethers would i need? 10, 20? guess it depends doesnt it

since the calc is pretty slow, ill start off with 20

got something done ig...

@viral token tell me why this wouldnt work??

i mean it did, but somewhere down the line.. it didnt.

i still have 1+1 hard wired to 3

maybe it didnt work, i think i need a bigger number to test it

lemme hook up some multiplication, although it is instant, it might prove a challenge

i think i broke it....

its now a tmr problem, server crashed 5 times today, cba anymore

[icy mauve]

its been 10 minutes and the server already crashed

[icy mauve]

did a quick redesign and it payed off, i tested it once and it works so that must mean it works for everything

💯

just to top it off the server crashed aswell

[icy mauve]

got quite a bit done since it didnt crash for 50 minutes,

• added a clear line for the equals button
• fixed the zero detection for line 1
• shut of 1 input side of the multiplier as it was giving double inputs
• connected multiplier to bcd

i only have a handful of things left to do before its 'done'

most of them is just connecting stuff to the bcd, specifically everything except the multiplier

then its just some small things thatll take like 2 minutes, such as closing the blockers once the answer goes through, equals line for input storage needs changing, the stable detection for the answer needs a lil something aswell and i still gotta wire some of the multiplexers for the divider and shorten one of the towers

[icy mauve]

all i did today was wire the multiplexers it only took 40 minutes, 4 crashes tho, apparently the crashes happen every 10 minutes now

on second thought i will NOT be shortening the tower because if i do, i will have to replace around 500 wires, and with these crashes every 10 mins, ill be there for a while.

it will look a bit dodgy, but not much i can do abt that

[icy mauve]

my 2 turned into a 3??

not looking forward to debugging dis...

ez fix, multiplier was still active couldnt get round to fixing it, server crashed

[icy mauve]

yayyyy 1+1 works

server crashed 4 times but i got it doneeee

im just gunna assume the rest all works cuz i aint got time, all thats left is to hook up division and debug the main loop thing cuz i tested that and it didnt work

[icy mauve]

I've stopped work on this project for the last few days cuz these server crashes are happening every 5 minutes its ridiculous
from when i hit join to when my base loads takes around 2 minutes itself, and the crash with the whole base deloading takes around 30 seconds, all in all im getting 2 minutes and 30 seconds of gameplay. it is borderline impossible to finish this since theres still so much to do,

imma just add up all the components and give an estimate of how much it costed

[icy mauve]

i have exactly 20,067 components placed with an ESTIMATED COST of 7,635,493.5

i would like to claim my crown of biggest logic build AND most expensive logic build

[grave stag]

So the point of this is for…

[icy mauve]

calculator

[grave stag]

Complex calculator?

Like it can do powers n such

Or a normal calculator

[icy mauve]

that was the plan, but before i could get to that bit the server started to crash

went from a crash every 20 minutes, to where it is now every 5 minutes

[grave stag]

You were so caught up in the fact you could

You didn’t think of whether you should…

Pretty kewl tho

[icy mauve]

its 17-bit BIANRY calculator

zero calculator components have been used, and no wire stacking either

also gotta say no google either, this came straight from the brain 🧠

[lavish vector]

and here i thought im pretty good by just making a weather reporter with decoder logic....

[fluid sluice]

Holy

Pretty sad that the server couldnt handle it

[wintry basalt]

Question does this use calculators or no

[icy mauve]

Not a single one 🤠

Ik u didnt ask, but im bored. I would say 50 - 60% of the entire build is adders, and all that is is just 1 OR gate, 2 AND gates and 2 XOR gates.

• For addition its just a plain adder stacked for however many bits you have
• Subtraction you have to flip some of the inputs/outputs
• Multiplication involves half adders and full adders, where the half adder is the output, and the full adder is the carry out (until u run out of main inputs the half adders stop)
• Division is a plain adder with a multiplexer on the end with the output shifting to the right one, but with a whole lot of seemingly complex wiring
• B.C.D. (binary coded decimal) I used the shift add 3 method and that's just addition so it's just a plain adder with a few extra detections for specific things

The point I'm tryna make is everything is just addition but manipulated, you could make an entire calculator using NAND gates if u wanted to

Also if u want a more detailed explanation of how every little thing works, I'm working on it.

[icy mauve]

Calculator Mk.3

Time for round 3! 🤙

[icy mauve]

most efficient shift register that i could think of, its pretty much instantaneous

doesnt use memory cells aswell

[torn echo]

and i thought my ai was cool

[potent arch]

What’s an calculator mk3 ?

[torn echo]

aint no way bro😭

[potent arch]

What can I do with the calculator

[viral token]

https://tenor.com/view/patrick-spongebob-spongebob-meme-patrick-meme-dumb-patrick-gif-9974665538168463324

[potent arch]

Aha

Funny guys

👍

[icy mauve]

the picture doesnt really do a lot, but believe me when i say it works flawlessly

i would send a video, the only way ik how is to upload it to youtube and send the link. but i aint doing allat 😭 🥀

[thick ravine]

does it draw graph or run python like a cg100 💀

[icy mauve]

Idk man, I dont think my calculator can run python 🤕

Im doing this in binary aswell, but graphing requires many operations

Its possible, but not feasible for me :/

[viral token]

you could do the graphing part using decimal

[icy mauve]

i mean i could, but i would still like to try it with binary

theres 100% a way, its just finding the most efficient path which is the hard part

[icy mauve]

I finished the shift register, but its not done yet since i want to include the amazing ability of removing your mistakes

simply a reverse shift in case u press the wrong thing

[young vigil]

Here we go again 😆

[icy mauve]

here's the finished shift register, very neat n tidy

this time i have to take the output from the shift register for the decimal to binary conversion, unlike the buttons from last time.

partially because i didnt plan ahead, but it will save me a lot of space this way too

and it should be faster and not rely on its own sperate shift register

[viral token]

pls make those tethers atleast blockers

[icy mauve]

I'll have to keep the top row but fine, I'll remove the tethers. Saves me having to wire an extra 100 too

[icy mauve]

It should NOT of taken 2 hours to finish the blockers, partially because i added a convergent layer for the operations so i wouldnt have to do something 4 times.

i call it selective laziness

[brittle coral]

Crazy im try to make a luck based machine and im not good in logic in game so i tryed with ai but im try to fix that for over 4 hours and dont work and after that i see this crazy builds

[icy mauve]

i hate this bit, it takes forever and looks rubbish but if i dont do it nothing will work.

[icy mauve]

doesnt look as bad as i thought it would, but it took forever.
well the miserable bits over with now, back to building a shifter!

[icy mauve]

somehow its turned out really organised, so much so space has been made for the multiplier spot so its out the way, the divider will have the middle and the small operations have their own spot too

[icy mauve]

the multiplication triangle is back

it'll be the same size as last time (approx 3/4 width of the plot). but this time you'll be able to see what goes where because previously it was a big blob of yellow which did my head in

[icy mauve]

half way done

[edgy jacinth]

What it's ?

2c f.adder 16bit ?

[icy mauve]

17bit multiplier

[icy mauve]

with no prior testing it works first try

next plan of action is to find a subtractor that works both ways

and a divider that makes sense to me, as last time i got hella confused with the outputs

[icy mauve]

negative numbers have been discovered

now that i have 3 operations fully working, time for the 2nd biggest time sink

✨ division ✨

[icy mauve]

division is stupidly hard

yk whats harder than division

getting the remainder to work

even the circuit gives u an out, just multiply the dividend by 100, or 1000 and u can skip the remainder entirely

thats called fixed point

i dont want to use fixed point.

i build 100% of divider, i use 100% of divider

wont matter for a while, i gotta build 4 more layers of the thing first

[icy mauve]

after looking into it a bit more, the simplest option (and most accurate) is to use fixed point. I figured i would but using it anyway, but my only problem with fixed point is that its really easy to get around and break it. thats why i wanted to use something else.

take for instance, 1 divided by 2. its simply 0.5, but using binary anything below 0 cannot be represented. so if u were to put that equation into my divider you would get 0 for the quotient and remainder 1 (0.1) instead of 0.5. this is because binary division uses LONG division, and since 1 - 2 is -1 it cannot show it.

simplest way to combat that is to just make 1 bigger, times it by 10. now the equation is 10 divided by 2, which the circuit can do easily. 5 for the quotient and 0 for the remainder. the answer is 5, but because we multiplied by 10, we divide by 10, just chuck in a 0 infront of the 5 and a decimal point and your set, easy work.

this is where the problem comes in, what if i make the divisor bigger. 10 divided by 20? same problem, divider cannot do it. what about 10 by 200? 2000? 20000?

well just multiply 1 by 100,000 and your set. well suddenly your 17 by 17 circuit has turned into 62 by 17. not very practical, plus i still have to build it too

most of the other solution are either even worse or not accurate for my scale

i could try and use 2's compliment which is what i did for my subtractor to gain access to negative numbers, but i dont know if thats even possible with division tbh

[icy mauve]

its so annyoing too cuz i only need this for numbers below 1 and above 0. other than that my divider works fine

[icy mauve]

after 2 and a bit hours of research and 17 google tabs, im convinced it is impossible without changing the size of the dividend. aka fixed point.

so i look forward to implementing a 62 by 17 bit divider and a 62 bit BCD unit

(i will be finding another soltuion, i do not want to deal with numbers in the 13 billions)

one of those solutions is to not care about it and make sure the dividend is always bigger than the divisor.... but that would be lazy of me.

[icy mauve]

oh and with this being a thing, the BCD unit alone will need around 26.4 THOUSAND components. (which is bigger than my other build in its entirety which uses 20.1k)

i NEED this workaround.

[low vale]

How? I must know!

[icy mauve]

2's complement!

[low vale]

?

[icy mauve]

its really only for binary if thats alright

but i can explain in detail if thats what u need

[icy mauve]

take the number you want to be negative, for instance 5. 5 in binary = 0101

then u flip all the bits to their opposite

so 0101 becomes 1010

then you simply add 1, so it become 1011

-5 = 1011

issue is 1011 is also equal to 11, the way u differentiate -5 from 11 is you sign the -5

add an extra bit to the left, if its 0 its positive, if its a 1 its negative

[low vale]

Hm

[icy mauve]

✨

[viral token]

that's cool i tought you'd just skedadle the adder etc with a flag

[icy mauve]

i should've clarified, 5 signed is 11011. since the left most bit is the part that clarifies if its positive or negative

and when put into the practice, the carry out is the sign bit

you are mostly right tho, since subtraction is just addition with extra steps, and the carry out is the sign (or flag)

[icy mauve]

i found the workaround

it was infront of my face the entire time.

divdend < divisor?
dividend + divisor = new dividend
new dividend / divisor

i hate how simple it is. 5 hours research for what...

[icy mauve]

its not that simple, it doesnt work.
I have 1 last idea though, but it means building a second divider and idk if it'll even work

[icy mauve]

Right, I have a method that works in theory and i'm 95% sure it will work. Big However, I'll need a looper, multiplier and some sort of memory system. 2 of which i'm not sure how to implement, but im glad i found a solution

or I can just build 15 dividers all of the same size

[icy mauve]

which is this number of components, 34,680.

[icy mauve]

smallest divider ever

[icy mauve]

time to spend a stupid amount of time trying to get this looper to work

[icy mauve]

i got the looper to work with no breaks so its constant, and when i remove the main input it stops, which is great.

its on the brink of completion, i just need stable detection for the divider outputs.

stable detection is the single most annoying thing ever alongside zero detection.

gimme a week or so and i'll have a solution

[thick ravine]

how many logic components did you use as of now?

[icy mauve]

Less than i thought, 8,514

[thick ravine]

💀

[icy mauve]

The design has arrived in my Brain. It is compact as it requires less than 30 parts whilst the other solution uses over 400.

[icy mauve]

simplest design ever, dunno why it took so long to figure out

[icy mauve]

time to re-build my looper, it works a little too well as its powering itself indefinitely

its too fast, i cant see what and where it goes wrong

[icy mauve]

I think i have a working design, but I dont really have a way to know if it works 100%....

i know for a fact the other designs didnt work, as they used memory cells.
i swapped this designs memory cells out for my SISO shifter and it seems to have worked

with my previous example, 1/2 should loop once then stop, it does just that. But then again it might not work with other equations, which is why i need an extra layer of security
