ERF function

This article describes the formula syntax and usage of the ERF function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

Description

Returns the error function integrated between lower_limit and upper_limit.

Syntax

ERF(lower_limit,[upper_limit])

The ERF function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

  • Lower_limit    Required. The lower bound for integrating ERF.
  • Upper_limit    Optional. The upper bound for integrating ERF. If omitted, ERF integrates between zero and lower_limit.

Remarks

  • If lower_limit is nonnumeric, ERF returns the #VALUE! error value.
  • If upper_limit is nonnumeric, ERF returns the #VALUE! error value.
