What is C# equivalent to ATAN(X,Y)?

Question

It looks like there are two parameters inside the atan function, but I'm not sure how to convert this to C#?

The IDL reference says "If two parameters are supplied, the angle whose tangent is equal to Y/X is returned. "

   atan(out[2,*],sqrt(out[0,*]^2+out[1,*]^2))
   atan(out[1,*],out[0,*])

Answer 1

this should do it no ?

using System;
radians = Math.Atan2(y, x);
