ATAND— Arctangent function, degrees
ATAND(X) computes the arctangent of X in degrees (inverse of
This function is for compatibility only and should be avoided in favor of standard constructs wherever possible.

|X||The type shall be |
|Y shall be of the same type and kind as X.|
The return value is of the same type and kind as X.
If Y is present, the result is identical to
Otherwise, it is the arcus tangent of X, where the real part of
the result is in degrees and lies in the range
-90 \leq \Re \atand(x) \leq 90.
