ATan2(Y, X)
ATan2: REAL function, the exact type being the result of cross-promoting the
types of all the arguments.
Y: REAL; scalar; INTENT(IN).
X: REAL; scalar; INTENT(IN).
Intrinsic groups: (standard FORTRAN 77).
Description:
Returns the arc-tangent (inverse tangent) of the complex number (Y, X) in radians.
See Tan Intrinsic, for the inverse of this function.
