D: A D package[16] exists providing efficient and accurate implementations of complex error functions, along with Dawson, Faddeeva, and Voigt functions.

• Mathematica: erf is implemented as Erf and Erfc in Mathematica for real and complex arguments, which are also available in Wolfram Alpha.
• Applied Mathematics Series. 55 (Ninth reprint with additional corrections of tenth original printing with corrections (December 1972); first ed.).
• Another approximation is given by erf ⁡ ( x ) ≈ sgn ⁡ ( x ) 1 − exp ⁡ ( − x 2 4 π + a x 2 1
• If x is the mean and y is the std dev I know that CI=(x-ny,x+ny), where n=sqrt(2)*inverseERF(CI).
• For complex, the Faddeeva package provides a C++ complex implementation.

Erf Function Excel erf(x) = GammaDist(x^2,0.5,1,True) so erfinv(p) = Sqrt(GammInv(p,0.5,1)) erfc(x) = ChiDist(2*x^2,1) so erfcinv(p) = Sqrt(ChiInv(p,1)/2) The ChiDist function is much more accurate for large x than the ATP erfc function.
