It is defined as:[1][2] erf ( x ) = 1 π ∫ − x x e − t 2 d t = 2 π ∫ 0 x e − t Supancic, "On Bürmann's Theorem and Its Application to Problems of Linear and Nonlinear Heat Transfer and Diffusion," The Mathematica Journal, 2014. http://blogeurope.net/error-function/gauss-error-function-excel.php

At the imaginary axis, it tends to ±i∞. 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. If L is sufficiently far from **the mean,** i.e. μ − L ≥ σ ln k {\displaystyle \mu -L\geq \sigma {\sqrt {\ln {k}}}} , then: Pr [ X ≤ L For previous versions or for complex arguments, SciPy includes implementations of erf, erfc, erfi, and related functions for complex arguments in scipy.special.[21] A complex-argument erf is also in the arbitrary-precision arithmetic dig this

If you need to, you can adjust the column widths to see all the data. The denominator terms are sequence A007680 in the OEIS. This is useful, for example, in determining the bit error rate of a digital communication system. http://www.excelfunctions.net/Excel-Erfc-Function.html Matlab provides both erf and erfc for real arguments, also via W.
