dense matrix
Hi! I'm currently using the meta option in DeluxeMenus to store and add values like this:
- '[meta] add customBoxKosztTotal DOUBLE 0.40'
The problem is that when I start from a number like 28.5 and add 0.40, the result becomes something like 28.89999999999998 instead of 28.9. It seems like there's a floating-point precision issue with how DOUBLE values are being added.
Is there any fix or workaround for this? I really need this to work properly as soon as possible.

this is fundamentally how doubles and all floating points work in all of computing
what is the use case here to need to be added with such precision?

I need precise calculations because I’m working on a "Wallet" system, and unfortunately, if a placeholder returns a value like 43.29999999999998, it looks messy and causes me to subtract an inaccurate amount from the player’s account. Is there any alternative I could use or a way to fix this issue? Something like that?

from your end i dont think so, i was thinking rounding within the math expansion, but this would cause further inaccuracies
@eager coyote i dont think its worth adding a BigDecimal data type to meta? :/
seems a bit too much

I simply need it to return 9.99 instead of 9.9999999999998, so that the command executed by the console can subtract the full amount for the product, instead of an inaccurate one
I struggled a bit with this wallet because I'm not that familiar with this topic, but it was only with the "custom box" product that this problem appeared :/
I don't have this problem with adding and subtracting 0.5, 1.0, but when I add or subtract the number 0.4, 0.8 this problem appears
