Math helper functions.

Traits

Implement the fast approximate computation of '1/sqrt(x)' for a type.

fast_invsqrt_32	Fast approximate computation of 1/sqrt(x). The error should be below 0.2%.
fast_invsqrt_64	Fast approximate computation of 1/sqrt(x). The error should be below 0.2%.
int_sqrt_floor	Compute square root of integers using Newtons method. Returns the biggest integer which is smaller or equal to the actual square root of `n`. Similar to `(i as f64).sqrt().floor() as T` but without type conversions.
