Documentation
quake_inverse_sq.coarse_inv_sqrt(number: float) -> float
This is fastest inverse square root algorithm. It is not as accurate as the quake_inverse_sq.fined_inv_sqrt function, but it is much faster. It is implemented from this wikipedia
quake_inverse_sq.fined_inv_sqrt(number: float) -> float
This is the original inverse square root algorithm. It is more accurate than the quake_inverse_sq.coarse_inv_sqrt function, but it is slower. It is implemented from math.h
