3.79. __nv_erfcinv

Prototype:

double @__nv_erfcinv(double %x)

Description:

Calculate the inverse complementary error function of the input argument y, for y in the interval [0, 2]. The inverse complementary error function find the value x that satisfies the equation y = erfc(x), for $0 \leq y \leq 2$ , and $- \infty \leq x \leq \infty$ .

Returns:

__nv_erfcinv(0) returns $+ \infty$ .
__nv_erfcinv(2) returns $- \infty$ .

Note:

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

Library Availability:
