__device__ float erfinvf ( float  y  ) 

Calculate the inverse error function of the input argument y, for y in the interval [-1, 1]. The inverse error function finds the value x that satisfies the equation y = erf(x), for $-1 \le y \le 1$, and $-\infty \le x \le \infty$.

Returns:
  • erfinvf(1) returns $\infty$.
  • erfinvf(-1) returns $-\infty$.
Note:
For accuracy information for this function see the CUDA C Programming Guide, Appendix C, Table C-1.
