Here is another way I found a few days ago.
Just insert this code into a standard module.
Function NumberChange(dblNum As Double, Optional bolArt As Variant)
Dim arrArt As Variant
Dim intCounter As Integer, intCts As Integer
Dim strValue As String, strTmp As String, strSuffix As String
On Error Resume Next
If bolArt = 1 Then
If Err = 0 Then
intCts = (dblNum - Fix(dblNum)) * 100
strSuffix = " " & Format(CStr(intCts), " 00") & "/100"
Else
bolArt = 0
End If
End If
On Error GoTo 0
dblNum = Fix(dblNum)
strTmp = Right(CStr(dblNum), 3)
strValue = Part(strTmp)
For intCounter = 1 To 4
strTmp = CStr(dblNum)
Select Case Len(strTmp)
Case Is < 1 + 3 * intCounter
NumberChange = strValue & strSuffix
Exit Function
Case Is < 4 + 3 * intCounter
strTmp = Left(strTmp, Len(strTmp) - intCounter * 3)
Case Else
strTmp = Left(Right(strTmp, 3 + intCounter * 3), 3)
End Select
Select Case intCounter
Case 1: arrArt = Array(" Thousand", " One Thousand")
Case 2: arrArt = Array(" Million", " One Million")
Case 3: arrArt = Array(" Billion", " One Billion")
Case 4: arrArt = Array(" Trillion", " One Trillion")
End Select
If Right(CStr(dblNum), 3) = "000" Then
strValue = Part(strTmp) & arrArt(0)
ElseIf CInt(strTmp) = 1 Then
strValue = arrArt(1) & strValue
Else
strValue = Part(strTmp) & arrArt(0) & strValue
End If
Next intCounter
NumberChange = strValue & strSuffix
End Function
