Returns the inverse tangent of x.


GML Code Example


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.


GML Code Example

val = arctan( 0 );

This will set val to 0.
