ERF Function

The ERF function is one of the engineering functions. It is used to calculate the error function integrated between the specified lower and upper limits.

The ERF function syntax is:

ERF(lower-bound [, upper-bound])

where

lower-bound is the lower limit of integration.

upper-bound is the upper limit of integration. It is an optional argument. If it is omitted, the function will calculate the error function integrated between 0 and lower-bound.

The numeric values can be entered manually or included into the cell you make reference to.

To apply the ERF function,

1. select the cell where you wish to display the result,
2. click the Insert function
