C# Class Sparrow.Utils.NumberUtil

Méthodes publiques

Méthode	Description
Clamp ( float value, float min, float max ) : float
Equals ( float a, float b ) : bool	checks if two numbers are equal with a small margin of error
FastCos ( float angle ) : float	Fast cosinus calculation with a look up table. Note that it is less accurate than Math.Cos; the largest error is around 0.3 degrees;
FastSin ( float angle ) : float	Fast sinus calculation with a look up table. Note that it is less accurate than Math.Sin; the largest error is around 0.3 degrees
NextPowerOfTwo ( float number ) : int
NextPowerOfTwo ( int number ) : int
