cerfi(3)

NAME
cerfi, erfi - imaginary error function

SYNOPSIS
#include <cerf.h>

double _Complex cerfi ( double _Complex z );

double erfi ( double x );

DESCRIPTION
The function cerfi returns an error function rotated in the complex plane, erfi(z) = -i erf(iz).

The function erfi takes a real argument and returns a real result.

SEE ALSO
The implementation of cerfi and erfi is trivially based on the functions cerf(3) and im_w_of_x(3).

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

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