3.6. __nv_asin

double @__nv_asin(double %x)

Calculate the arc sine of the input argument.

Calculate the principal value of the arc sine of the input argument x.

Note

For accuracy information, see the CUDA C++ Programming Guide, Mathematical Functions Appendix, Double-Precision Floating-Point Functions section.

Returns

Result will be in radians, in the interval [- \(\pi\) /2, + \(\pi\) /2] for x inside [-1, +1].

• __nv_asin(0) returns +0.

• __nv_asin(x) returns NaN for x outside [-1, +1].
