|
* This function calculates the arc tangent of the two variables x and y. It is similar to |
45

* calculating the arc tangent of y ÷ x, except that the signs of both arguments are used |
46
|
|

* to determine the quadrant of the result. |
47

|
|
* The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a |
48
|
|
|
* point with coordinates (xCoordinate, yCoordinate). The angle is given in radians between |
49

|
* -pi and pi, excluding -pi. |
