Changing value bug

Help and Feedback Scripting Support
#1

I’ve experienced a bug that I cannot get around. I have no clue how this has occurred. Only one script is updating the value.

Code:

value.Value = value.Value - 0.1

Result:
2.9
2.8

Welcome to floating-point error :partying_face: !

Because of the nature of how decimals are stored on computers, this happens. It is not a bug. If it really messes with your code, try using whole numbers instead of decimals.
