WebThe atan2 () functions return a value in the range -pi to pi radians. If both arguments of atan2 () are zero, the function sets errno to EDOM, and returns 0. If the correct value would cause underflow, zero is returned and the value ERANGE is stored in errno. Special behavior for IEEE: If successful, atan2 () returns the arctangent of y/x.

WebThe atan() function returns a value in the range -π/2 to π/2 radians. The atan2() function returns a value in the range -π to π radians.
