Returns the inverse tangent of x. This will accept any number as, unlike tan(), arctan() 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.
NOTE: This function takes a value in radians, not degrees.
arctan(x);
| Argument | Type | Description |
|---|---|---|
| x | Real | The angle (in radians) to return the inverse tangent of. |
val = arctan( 0 );
This will set val to 0.
