erfi (3)

#include <cerf.h>

double _Complex cerfi ( double _Complex z );

double erfi ( double x );

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.

The implementation of cerfi and erfi is trivially based on the functions cerf and im_w_of_x.

Please report bugs to the authors.
