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.
