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

NAME
       cerfcx, erfcx - underflow-compensated complementary error function

SYNOPSIS
       #include	<cerf.h>

       double _Complex cerfcx (	double _Complex	z );

       double	       erfcx  (	double x );

DESCRIPTION
       The function cerfcx is an underflow-compensated variant of the complex
       error function: erfcx(z)	= exp(z^2) erfc(z).

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

REFERENCES
       The implementation of cerfcx is a thin wrapper around Faddeeva's
       function	w_of_z.

       The implementation of erfcx is self-contained, and improves upon	the
       SLATEC DERFC function (or an erfcx function derived therefrom) or
       Cody's CALERF function (from netlib.org/specfun), while retaining near
       machine precision in accuracy.

SEE ALSO
       Related complex error functions in liberfc: w_of_z(3), dawson(3),
       voigt(3), cerf(3), erfi(3).

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