ASIND — Arcsine function, degrees#

ASIND(X)#

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

Parameters

X – The type shall be either REAL and a magnitude that is less than or equal to one - or be COMPLEX.

Returns

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.

Standard:

GNU extension, enabled with -fdec-math.

Elemental function

Syntax:
RESULT = ASIND(X)
Example:
program test_asind
  real(8) :: x = 0.866_8
  x = asind(x)
end program test_asind
