         researched the numerics, and implemented the Faddeeva function.

       Joachim Wuttke <j.wuttke@fz-juelich.de>, Forschungszentrum Juelich,
         reorganized the code into a library, and wrote this man page.

       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.

       cerfi, erfi - imaginary error function

       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).
