Summary

Mathematics (from Greek μάθημα máthēma, "knowledge, study, learning") includes the study of such topics as quantity, structure, space, and change.

---

• float PI

Return a precise enough value of PI as float

• Type max( Type a, Type b )

Return the maximum value, Type can be one of: int, float, long, double

• Type min( Type a, Type b )

Return the minimum value, Type can be one of: int, float, long, double

• Type abs( Type a )

Return the absolute value, Type can be one of: int, float, long, double

• float floor( float a )

Return the largest integer less than or equal to a

• float round( float a )

Return the value of a rounded to the nearest integer

• float ceil( float a )

Return the smallest integer greater than or equal to a

• float random()

Return a random float that is greater than or equal to 0 and less than 1 In other words, returns a value x such that x >= 0 && x < 1

• int random( int min, int max )

Return a random int that is greater than or equal to min and less than max In other words, returns a value x such that x >= min && x < max

• float cos( float angle )

Return the cosine of the angle expressed in radians (example)

• float sin( float angle )

Return the sine of the angle expressed in radians (example)

• float atan2( float fy, float fx )

Returns the arctangent of the quotient of its arguments, as a numeric value between PI and -PI radians. The number returned represents the counterclockwise angle in radians between the positive X axis and the point (x, y).

• float sqrt( float x )

Return the square root of the float value passed
