3.7. __nv_asinf

float @__nv_asinf(float %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, Single-Precision Floating-Point Functions section.

Returns

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

• __nv_asinf(0) returns +0.

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