Method	Description
FastCos ( float x ) : float	Calculates the approximate value of cosine function at a given angle. This function is much faster than `Mathf.Cos()`, especially on mobile devices.
FastInvSqrt ( float x ) : float	Calculates the approximate inverse square root of a given value. This function is much faster than calling `1/Mathf.Sqrt(x)`, especially on mobile devices.
FastIsNaN ( float x ) : bool	Checks whether the float value is NaN. This function is much faster than calling `Math.IsNaN()`, especially on mobile devices.
FastLog2 ( float x ) : float	Calculates the approximate log2 of a given value. This function is much faster than `Mathf.Log()`, especially on mobile devices.
FastPow ( float a, float b ) : float	Calculates the approximate value of a^b. This function is much faster than `Mathf.Pow()`, especially on mobile devices.
FastPow2 ( float x ) : float	Calculates the approximate value of 2^x. This function is much faster than `Mathf.Pow()`, especially on mobile devices.
