Calculate the principal value of the arc sine of the input argument x
.
- Returns:
- Result will be in the interval [-
, +
] for x
inside [-1, +1].
- asinf(0) returns +0.
- asinf(
x
) returns NaN for x
outside [-1, +1].
- Note:
- For accuracy information for this function see the CUDA C Programming Guide, Appendix C, Table C-1.
