WebThe C function atan2, and most other computer implementations, are designed to reduce the effort of transforming cartesian to polar coordinates and so always define atan2(0, 0). On … WebThe atan2 () function returns a value in the range -π to π radians. If both arguments of the atan2 () function are zero, the function sets errno to EDOM, and returns a value of 0. Example This example calculates arctangents using the atan () and atan2 () functions.
