Class AstarMath

float DeltaAngle (

float	angle1
float	angle2

)

Calculates the shortest difference between two given angles given in radians.

The return value will be between -pi/2 and +pi/2.

string FormatBytesBinary (

int

bytes

)

Returns a nicely formatted string for the number of bytes (KiB, MiB, GiB etc).

Uses decimal names (KB, Mb - 1000) but calculates using binary values (KiB, MiB - 1024)

Color HSVToRGB (

float	h
float	s
float	v

)

Converts an HSV color to an RGB color.

According to the algorithm described at http://en.wikipedia.org/wiki/HSL_and_HSV

Color IntToColor (

int	i
float	a

)

Returns a nice color from int i with alpha a.

Got code from the open-source Recast project, works really well. Seems like there are only 64 possible colors from studying the code

float MapTo (

float	startMin
float	startMax
float	targetMin
float	targetMax
float	value

)

Maps a value between startMin and startMax to be between targetMin and targetMax.

long SaturatingConvertFloatToLong (

float

v

)

Converts a non-negative float to a long, saturating at long.MaxValue if the value is too large.

int Bit (

int	a
int	b

)

Returns bit number b from int a.

The bit number is zero based. Relevant b values are from 0 to 31. Equals to (a >> b) & 1
