NAME
       cerf, cerfc - complex error functions

SYNOPSIS
       #include <cerf.h>

       double _Complex cerf ( double _Complex z );

       double _Complex cerfc ( double _Complex z );

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 complementary complex error function cerfc is defined as erfc(z) =
       1-cerf(z).

SEE ALSO
       The computations are based on Faddeeva's function w_of_z(3).

       Other complex error functions in libcerf: w_of_z(3), dawson(3),
       voigt(3), erfcx(3), erfi(3).

       The real error function comes with recent versions of glibc, as
       requested by the C99 standard: erf(3)
