3.244. __nv_normcdfinv

Prototype:

double @__nv_normcdfinv(double %x)

Description:

Calculate the inverse of the standard normal cumulative distribution function for input argument y, $Φ^{- 1} (y)$ . The function is defined for input values in the interval $(0, 1)$ .

Returns:

__nv_normcdfinv(0) returns $- \infty$ .
__nv_normcdfinv(1) returns $+ \infty$ .
__nv_normcdfinv(x) returns NaN if x is not in the interval [0,1].

Note:

For accuracy information for this function see the CUDA C Programming Guide, Appendix D.1, Table 7.
