Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Other than that everything works

#

oh shit

#

0.3/0.1 is 2.9999999999997

#

in the integer of that is 2

#

why?????

#

the calculator says 3

#

python says 2.99999997

#

that must be a python error!!!

#

so i need to use the round function then

chrome zenith
#

int() just takes whatever float number you have and removes the decimals, it doesn't round

stone moth
#

yes so ill use round instead

#

but i dont understand why python says that 0.3/0.1 is 2.999999999999997

#

because it is exactly 3

#

the real answer is exactly 3

oh i see

#

thats why

chrome zenith
#

computers use binary to represent numbers, you cannot have infinite number of binaries in your computer, so you cannot perfectly characterise every number

stone moth
#

i see

#

good to know

#

so ill use round() instead

#

it rounds to nearest integer

#

thanks for your help @chrome zenith

#

greatly appreciated!
