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 __sinf() by __cosf(). Denormal input and output are flushed to sign-preserving 0.0 at each step of the computation.
