Méthode Description
BinomialCoefficient ( int n, int k ) : long

Calculates the binomial coefficient n above k.
DegreesToRadians ( float degrees ) : float

Convert degrees to radians
Factorial ( int n ) : long

Calculates the factorial of a given natural number.
InverseSqrtFast ( double x ) : double

Returns an approximation of the inverse square root of left number.

This is an improved implementation of the the method known as Carmack's inverse square root which is found in the Quake III source code. This implementation comes from http://www.codemaestro.com/reviews/review00000105.html. For the history of this method, see http://www.beyond3d.com/content/articles/8/
