  • Analytic Theory of Continued Fractions.
  • Mathematica: erf is implemented as Erf and Erfc in Mathematica for real and complex arguments, which are also available in Wolfram Alpha.
  • For complex double arguments, the function names cerf and cerfc are "reserved for future use"; the missing implementation is provided by the open-source project libcerf, which is based on the Faddeeva

Erf(inf) It is unfortunate that changes from Glaisher’s original $\mathrm{Erf}$: the switch of limits, names and the standardizing factor, did not apply to what Glaisher acknowledged was its most important application: the Orlando, FL: Academic Press, pp.568-569, 1985. Fortran 77 implementations are available in SLATEC.
