However, we'll need to audit the description of each function to cleanup the non-support for complex. For example, ASIND has _Arguments_: X The type shall be either ‘REAL’ and a magnitude that is less than or equal to one - or be ‘COMPLEX’. _Return value_: 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 -90 \leq \Re \asin(x) \leq 90. These should likely read _Arguments_: X The type shall be ‘REAL’. The magnitude of X should be less than or equal to one. _Return value_: The return value is of the same type and kind as X. The result is in degrees and lies in the range -90 \leq \Re \asin(x) \leq 90.
