3.245. __nv_normcdfinvf

Prototype: 

float @__nv_normcdfinvf(float %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_normcdfinvf(0) returns − ∞ .

  • __nv_normcdfinvf(1) returns + ∞ .

  • __nv_normcdfinvf(x) returns NaN if x is not in the interval [0,1].
