8.20 ASIND — Arcsine function, degrees

Description:
ASIND(X) computes the arcsine of its X in degrees (inverse of SIND(X)).

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

Standard:
GNU extension, enabled with -fdec-math.
Class:
Elemental function
Syntax:
RESULT = ASIND(X)
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.
Example:
          program test_asind
            real(8) :: x = 0.866_8
            x = asind(x)
          end program test_asind
     

Specific names:
