DESCRIPTION The function cerf() is the complex version of the error function. erf(z) = 2/sqrt(pi) * integral from 0 to z of exp(-t*t) dt. The func- tion cerfc() is defined as cerfc(z) = 1-cerf(z).

CONFORMING TO The function names are reserved for future use in C99.

AVAILABILITY Not yet in glibc, as at version 2.4.
