Intel® Fortran Compiler 18.0 Developer Guide and Reference
Elemental Intrinsic Function (Generic): Produces the arcsine of an argument.
result = ASIN (x)
x |
(Input) Must be of type real, where | x | must be less than or equal to 1, or of type complex. |
The result type and kind are the same as x.
If the result is real, it is expressed in radians and lies in the range - pi/2 <= ASIN (x) <= pi/2.
If the result is complex, the real part is expressed in radians and lies in the range pi/2 <= REAL (ASIN (x)) <= pi/2.
