Syntax

public static native double atan2( double a**, double** b )

Parameters
  • a
    a double value.
  • b
    a double value.
Returns

the theta component of the point (r, theta) in polar coordinates that corresponds to the point (b, a) in Cartesian coordinates.

Description

Converts rectangular coordinates (b, a) to polar (r, theta). This method computes the phase theta by computing an arc tangent of b/a in the range of -pi to pi.
