build::libcerf::src::libcerf::man::erfi(3) libcerf manual NAME cerfi, erfi - imaginary error function SYNOPSIS #include 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).
