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 for this function see the CUDA C Programming Guide, Appendix C, Table C-4.

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.

Library Availability:

Compute 2.0: Yes

Compute 3.0: Yes

Compute 3.5: Yes
