Fixed point mathematics
WebTo make a fixed point number, all that we do is place this decimal somewhere in the middle. As an example, we’ll decide that the decimal point is between bits 14 and 15. Mostly, this is just the way that we now think about … WebApr 10, 2024 · This library implements "Fix64", a 64 bit fixed point 31.32 numeric type and transcendent operations on it (square root, trig, etc). It is well covered by unit tests. However, it is still missing some operations; in particular, Tangent is not well tested yet.
