!!DESCRIPTION |

|
| |
|
23 |
The __atan2()__ function calculates the arc tangent of |
| |
|
24 |
the two variables ''x'' and ''y''. It is similar to |
| |
|
25 |
calculating the arc tangent of ''y'' / ''x'', except |
| |
|
26 |
that the signs of both arguments are used to determine the |
| |
|
27 |
quadrant of the result. |
| |
|
28 |
!!RETURN VALUE |
| |
|
29 |
|
| |

|
| |
|
31 |
The __atan2()__ function returns the result in radians, |
| |
|
32 |
which is between -PI and PI (inclusive). |
