Value in array cannot be updated VBA Excel

Question

I am trying to get the nth similar of a range compare to a text. The Similarity function is to return a percentage similarity between 2 texts.

Function SimilarText(ByVal CompareText As String, _
                    ByRef TargetCompare As Range, _
                    Optional ByVal RankSimilarity As Integer = 1) As Long

Dim compareResults() As Long
ReDim compareResults(RankSimilarity)
Dim simiResult As Single
Dim smallestIndex As Integer
Dim result As String
Debug.Print (CompareText)

For Each cell In TargetCompare
    simiResult = Similarity(cell.Value, CompareText)
    Debug.Print (simiResult)
    If simiResult > Application.Min(compareResults) Then
        smallestIndex = Application.Match(Application.Min(compareResults), compareResults, 0) - 1
        Debug.Print ("Index:" & smallestIndex)
        compareResults(smallestIndex) = CLng(simiResult)'//This doesnt seem to do anything. I tried without the conversion but still nothing.
        Debug.Print ("Smallest after update:" & compareResults(smallestIndex)) '//This always 0
    End If
Next cell

    SimilarText = Application.Min(compareResults) '//So this is also alway 0

End Function

I would expect the array element will be updated after each cell like '(0.22,0.44) but the result seems to always be 0.

Answer 1

Your array compareResults() is defined as Long, and that's only for integer numbers.

Long data type (Visual Basic)

Change data type to something that admits decimal.

Also, in line compareResults(smallestIndex) = CLng(simiResult), you are forcing a number to become a long integer. Use somethin else, or it will save a long integer number.
