3.263. __nv_normcdfinv

double @__nv_normcdfinv(double %x)

Calculate the inverse of the standard normal cumulative distribution function.

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

Note

For accuracy information, see the CUDA C++ Programming Guide, Mathematical Functions Appendix, Double-Precision Floating-Point Functions section.

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].
