ERF

ERF function : It Returns the error function integrated between lower_limit and upper_limit.


Syntax
ERF(lower_limit,upper_limit)

Lower_limit   is the lower bound for integrating ERF.
Upper_limit   is 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 lower_limit is negative, ERF returns the #NUM! error value.
• If upper_limit is nonnumeric, ERF returns the #VALUE! error value.
• If upper_limit is negative, ERF returns the #NUM! error value. [Equation]
