3.118. __nv_fast_tanf

float @__nv_fast_tanf(float %x)

Calculate the fast approximate tangent of the input argument.

Calculate the fast approximate tangent of the input argument x, measured in radians.

Note

For accuracy information, see the CUDA C++ Programming Guide, Mathematical Functions Appendix, Intrinsic Functions section.

Note

The result is computed as the fast divide of __nv_sinf() by __nv_cosf(). Denormal input and output are flushed to sign-preserving 0.0 at each step of the computation.

Returns

Returns the approximate tangent of x.
