Openoffice Macro Script for function to convert numbers to string

Paste this script in a new module in Tools->Organize macros->Openoffice.org Basic->My Macros

This is not a script developed by me. I have debugged the original version for a error when it had to deal with amount less than 10 Paise. I am using it for my OO installation.
==================
Function SpellNumber(ByVal MyNumber)

Dim Rupees, Paise, Temp
Dim DecimalPlace, Count, DeciUnit
Dim Place() as string



ReDim Place(9) As String

Place(2) = "Thousand "

Place(4) = "Crore "
Place(5) = "Arab "
Place(6) = "Kharb "

' String representation of amount.

If MyNumber < 1 Then
MyNumber = Trim(Str(MyNumber))
DeciUnit = InStr(MyNumber, "E")
If DeciUnit > 0 Then
MyNumber = "0.0" + left(MyNumber,1)
End If
Else
MyNumber = Trim(Str(MyNumber))
End If



' Position of decimal place 0 if none.
DecimalPlace = InStr(MyNumber, ".")
' Convert Paise and set MyNumber to Rupee amount.
If DecimalPlace > 0 Then
Paise = GetTens(Left(Mid(MyNumber, DecimalPlace + 1) & _
"00", 2))
MyNumber = Trim(Left(MyNumber, DecimalPlace - 1))
Else
Paise = ""
End If

Count = 1
if MyNumber <> "" then
Temp = GetHundreds(Right(MyNumber, 3))
If Temp <> "" Then Rupees = Temp & Place(Count) & Rupees
If Len(MyNumber) > 3 Then
MyNumber = Left(MyNumber, Len(MyNumber) - 3)
Else

End If
Count = Count + 1
