Although it appears you are using whole integers when doing the calculations, I wonder if there might still be floating point issues.  
In general, I’d advice against compares using “==”, since these are floating point numbers. Ofc, if it _is_ guarantueed to be whole numbers, it should be ok.  
You can read a bit more about floating point precision [here](https://forum.defold.com/t/floating-point-precision/11247).
