).
This function is for compatibility only and should be avoided in favor of standard constructs wherever possible.

Elemental function
RESULT = ACOSD(X)
X | The type shall either be REAL with a magnitude that is less than or equal to one - or the type shall be COMPLEX . |
The return value is of the same type and kind as X. The real part of the result is in degrees and lies in the range 0 \leq \Re \acos(x) \leq 180.
