C++ std atan2
WebThe atan() and atan2() functions calculate the arctangent of x and y/x, respectively. Return Value. The 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. If both arguments of the atan2() function are zero, the function sets errno to EDOM, and returns a value ...
