Inverse tangent of ratio of arguments
Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is currently no direct OO equivalent for the $ArcTan2 function.
The $ArcTan2 function returns the arctangent (in radians) of the ratio of two arguments — x divided by y. If the second argument is 0 (or omitted), an error message is printed and a 0 is returned.
Syntax
%num = $ArcTan2(x,y)
