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])
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,
- select the cell where you wish to display the result,
- click the Insert Function icon situated at the top toolbar,
or right-click within a selected cell and select the Insert Function option from the menu,
or click the icon situated at the formula bar,
- select the Engineering function group from the list,
