ASIN(X)
computes the arcsine of its X (inverse of SIN(X)
).
Fortran 77 and later, for a complex argument Fortran 2008 or later
Elemental function
RESULT = ASIN(X)
X | The type shall be either REAL and a magnitude that is less than or equal to one - or be COMPLEX . |
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 \leq \Re \asin(x) \leq \pi/2.
program test_asin real(8) :: x = 0.866_8 x = asin(x) end program test_asin
