9.20 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:
