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 <= asin(x) <= PI/2.
EXAMPLE
Sample program:
program demo_asin real(8) :: x = 0.866_8 x = asin(x) end program demo_asin
