# ERF

ERF(lower_limit [,upper_limit])

Returns the value of the error function integrated between two limits.

 lower_limit The lower bound. upper_limit (Optional) The upper bound.

 REMARKS
 * Also known as the Gaussian Error Integral.* If any of the arguments are not numeric, then #VALUE! is returned.* If "lower_limit" > "upper_limit", then #N/A is returned.* If "lower_limit" is left blank, then #N/A is returned.* If "upper_limit" is left blank, then 0 is used.* This function is similar to the ERF.PRECISE.* For the Microsoft documentation refer to support.microsoft.com* For the Google documentation refer to support.google.com
