arctan(x);
| Argument | Description |
|---|---|
| x | The angle (in radians) to return the inverse tangent of. |
Returns: Real
Returns the inverse tangent of x. This will accept any number
as, unlike tan, arctans asymptotes are on the y axis so it just
means you'll never get returned a number greater than pi/2 or less
than -pi/2.
val = arctan( 0 );
This will set val to 0.
