float @__nv_fast_powf(float %x, float %y)

Calculate the fast approximate of \(x^y\).

Calculate the fast approximate of x, the first input argument, raised to the power of y, the second input argument, \(x^y\).

Note

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

Note

Most input and output values around denormal range are flushed to sign preserving 0.0.
