3.84. __nv_erfinv
Prototype:
double @__nv_erfinv(double %x)
Description:
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 , and .
Returns:
-
__nv_erfinv(1) returns .
-
__nv_erfinv(-1) returns .
