3.110. __nv_fast_tanf
Prototype:
float @__nv_fast_tanf(float %x)
Description:
Calculate the fast approximate tangent of the input argument x, measured in radians.
Returns:
Returns the approximate tangent of x.
Note:
For accuracy information see the CUDA C++ Programming Guide, Mathematical Functions Appendix, Intrinsic Functions section.
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.
