(int) (round(19.33, 2) * 100) = 1932 - can someone please explain this to me?
Besides, using an arbitrary-precision library gives you an unlimited number of digits, and, in the case of brick/math, many more rounding modes to choose from. And predictable ones.
TL;DR: don't use floats if you ever need to rely on rounding. Use an arbitrary-precision arithmetic library such as brick/math. Example:
