ASIN(3f)

DESCRIPTION
ASIN(X) computes the arcsine of its X (inverse of SIN(X)).

STANDARD
Fortran 77 and later, for a complex argument Fortran 2008 or later

CLASS
Elemental function

SYNTAX
RESULT = ASIN(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 radians and lies in the range -PI/2 <=q Re asin(x) <=q PI/2.

EXAMPLE
          program test_asin
            real(8) :: x = 0.866_8
            x = asin(x)
          end program test_asin
