UPDATE Looking at the code it seems you are just stuffing the … WebChanging fixed point representations is commonly called 'scaling'. If you can do this with a class with no performance penalty, then that's the way to go. It depends heavily on the compiler and how it inlines.

Unlike floating-point operations, fixed-point math numbers represent real number with less precision as they have a fixed number of bits to represent a number before and after the decimal point. For example, if we have 16-bit number in 1.15 fixed-point format, the 16-bit value can …
