The inverse of the tangent function is known as arc tangent, most math libraries shorten this to atan or atan2. The trig functions are many to one, therefore the 

Returned values are in radians, degrees or gradians, depending upon the system Atan2 Calculator. The arc tangent function with two arguments is called as the atan2. It can be represented as atan2(y,x). It was initially used by the computer programming languages and now it has been used in various science and engineering fields.

Portability: ISO/ ANSI C conforming, UNIX compatible  This module provides access to the mathematical functions defined by the C For example, atan(1) and atan2(1, 1) are both pi/4 , but atan2(-1, -1) is -3*pi/4 .

The function calls atan2 (unqualified) once for each element in both x and y; If either is a single T value, it is used for all calls. The Excel ATAN2 function returns the arctangent from the x and y coordinates of a point.

Contains detailed descriptions of the Intel IPP functions and interfaces for signal, image processing, and computer vision.
