Открытые методы

Метод	Описание
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/
NextPowerOfTwo ( double n ) : double	Returns the next power of two that is larger than the specified number.
NextPowerOfTwo ( float n ) : float	Returns the next power of two that is larger than the specified number.
NextPowerOfTwo ( int n ) : int	Returns the next power of two that is larger than the specified number.
NextPowerOfTwo ( long n ) : long	Returns the next power of two that is larger than the specified number.
RadiansToDegrees ( float radians ) : float	Convert radians to degrees
Swap ( double &a, double &b ) : void	Swaps two double values.
Swap ( float &a, float &b ) : void	Swaps two float values.
