This is due to floating point precision.

You can [read more about it here](https://forum.defold.com/t/floating-point-precision/11247)

In short, unless you are certain that the number can be accurately represented (e.g. whole numbers), you are best advised to not do “==” comparisons with floating point numbers.

An alternative is to see if the number “is close” to the number you desired: `if abs(a - b) < 0.001 then ...`. Although I’d look into other ways of detecting these scenarios instead.
