Convert Money to Indian Currency Format

I searched in google an found nothing on converting money to indian currency format, there were some codes to convert money to U.S currency format. So i decided to write one for my own.

here is the function

CREATE FUNCTION dbo.udf_MoneyFormat
(
@amount MONEY
)
RETURNS VARCHAR(50)
AS

BEGIN
     DECLARE @charMoney VARCHAR(50), @RemainingChar VARCHAR(50)
     ,QuotChar VARCHAR(50)
     DECLARE @LenStr INT, @val INT, @index INT
     SELECT @charMoney = CONVERT(VARCHAR(50),@amount)
     SELECT @QuotChar = SUBSTRING(@charMoney,1,CHARINDEX('.',@charMoney)-1)
     SELECT @val = LEN(@charMoney) - LEN(@QuotChar)
     SELECT @RemainingChar = SUBSTRING(@charMoney,CHARINDEX('.',@charMoney),@val)
     SELECT @LenStr = LEN(@QuotChar) 
     SET @index = 3
     WHILE (@LenStr > @index)
     BEGIN
         SET @QuotChar = (SELECT STUFF(@QuotChar, (@LenStr-@index) + 1, 0, ','))
         SET @index = @index + 2
     END    
     RETURN @QuotChar + @RemainingChar
END

DECLARE @amount Money
SET @amount = 1000023.08
SELECT dbo.udf_MoneyFormat(@amount)

RESULT:
-------
10,00,023.08
