Member Function Documentation

atan2()

static float java.lang.Math.atan2 ( float  fy, float  fx  )

static

Returns the angle theta from the conversion of rectangular coordinates (x, y) to polar coordinates (r, theta).

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

Returns

An angle expressed in radians, between the values of -PI and PI.

max() [1/2]

static byte java.lang.Math.max ( byte  a, byte  b  )

static

Returns the greater of two byte values.

Note

This function is non-standard

max() [2/2]

static uint java.lang.Math.max ( uint  a, uint  b  )

static

Returns the greater of two uint values.

Note

This function is non-standard

min() [1/2]

static byte java.lang.Math.min ( byte  a, byte  b  )

static

Returns the lesser of two byte values.

Note

This function is non-standard
