wrkdirs::usr....4::man::erfi(3)	libcerf	manual wrkdirs::usr....4::man::erfi(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).
