ERF

Calculates the error function (Gauss error function).

This function is only available if the Analysis AddIn is installed.

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:

ERF(x₁; x₂) is ERF(x₂) - ERF(x₁).

Example:

ERF(0.5)

returns 0.520499877813.

ERF(0.2; 0.5)

returns 0.297797288603.
