ASIN — Arcsine function#
-
ASIN(X)#
ASIN(X)
computes the arcsine of itsX
(inverse ofSIN(X)
).- Parameters
X – The type shall be either
REAL
and a magnitude that is less than or equal to one - or beCOMPLEX
.- Returns
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.
- Standard:
Fortran 77 and later, for a complex argument Fortran 2008 or later
- Class:
Elemental function
- Syntax:
RESULT = ASIN(X)
- Example:
program test_asin real(8) :: x = 0.866_8 x = asin(x) end program test_asin
