AutoIt is a freeware automation language for Microsoft Windows. In its earliest release, the software was primarily intended to create automation scripts (sometimes called macros) for Microsoft Windows programs but has since grown to include enhancements in both programming language design and overall functionality. While the scripting language in AutoIt 1 and 2 was statement-driven, designed primarily for simulating user interaction, from version 3 onwards the AutoIt syntax is similar to that found in the BASIC family of languages.

    If @error Then Exit

    ; Display the result in a message box.
    MsgBox($MB_OK, "Find Average", "Result: " & $fAverage)
EndFunc   ;==>_Example

Func _Find_Average($aArray)
    ; If the input is not of the correct type (an array), then return an error along with the details.
    If Not IsArray($aArray) Then Return SetError(1, 0, VarGetType($aArray))
	; More detailed checks are possible, but for brevity just one is performed here.

    ; Declare a variable to store the sum of the numbers.
    Local $iArraySum = 0

    ; Loop through the array.
    For $i = 1 To $aArray[0]
        ; Increment the sum by the number in each array element.
        $iArraySum += Number($aArray[$i])
    Next

    ; Return the average rounded to 2 decimal places.
    Return Round($iArraySum / $aArray[0], 2)
