About This Tool

The online Error Function Calculator is used to calculate the error function of a given number.

Error Function

In mathematics, the error function is a special function (non-elementary) of sigmoid shape which occurs in probability, statistics and partial differential equations. It is also called the Gauss error function or probability integral.

The error function is defined as:
