Inverse of the complementary error function.
Computes the inverse of the complementary error function.
In the complex domain, there is no unique complex number w satisfying erfc(w)=z. This indicates a true inverse function would have multi-value. When the domain restricts to the real, 0 < x < 2, there is a unique real number satisfying erfc(erfcinv(x)) = erfcinv(erfc(x)).
It is related to inverse of the error function by erfcinv(1-x) = erfinv(x)
