ERF

The ERF function returns the integral of the Gauss error function over an interval of values.

Parts of an ERF formula

ERF(lower_bound, [upper_bound])

Part	Description	Notes
lower_bound	If this parameter is the only parameter, the integral is taken between 0 and this value. If z2 is provided, it refers to the lower boundary for the integral.
upper_bound	The upper boundary of the integral.	Upper boundaries are optional.

Sample formulas

ERF(-2.3, -0.7)

ERF(1)

Notes

If the lower or upper boundaries are non-numeric, ERF returns “#VALUE!.”
