`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
