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