Definite integrals are given by (11) (12) (13) (14) (OEIS A087197 and A114864), where is the Euler-Mascheroni constant and is the natural logarithm of 2.

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.

Related functions[edit] The error function is essentially identical to the standard normal cumulative distribution function, denoted Φ, also named norm(x) by software languages, as they differ only by scaling and translation.

i was able to recode the pascal invERF function into vba. Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables. ISBN0-486-61272-4. However, in Excel 2010, the function algorithm has been improved, so that it can now calculate the function for both positive and negative values of x.Erfc Function ExamplesIn the following spreadsheet,
