atan

atan returns either the angle whose

trigonometric arctangent is y \over x or

y_over_x, depending on which overload is

invoked. In the first overload, the signs of y and x are

used to determine the quadrant that the angle lies in. The value

returned by atan in this case is in the

range [-π,π]. The result is undefined if x = 0.

For the second overload, atan returns the

angle whose tangent is y_over_x. The

value returned in this case is in the range

[-{π \over 2 },{π \over 2}].
