ATan(x:Num, [y:Num]):Num
Returns the arc-tangent of x resp. x/y. The angle is returned in degrees (not radians as many other programming languages), and is in the range [0,360).
A heading angle is computed as
angle := ATan(Waypoint.DX, Waypoint.DY)
This form is better than
angle := ATan(Waypoint.DX / Waypoint.DY)
because it gets the quadrant right, and does not divide by zero if Waypoint.DX is 0.
If any parameter is EMPTY, or if both parameters are 0, returns EMPTY.
