Calculates the error function (Gauss error function).

Syntax:

ERF(number1, number2)

if number2 is omitted, returns the error function calculated between 0 and number1, otherwise returns the error function calculated between number1 and number2. The error function, also known as the Gauss error function, is defined for ERF(x) as:






Example:

ERF(0.5)
returns 0.520499877813.
ERF(0.2; 0.5)
returns 0.297797288603.
