Hello,

You can use this code

http://www.codeproject.com/KB/vbscript/CurrencyToWord.aspx

Or you can simply go backward using following logic

Divide your maximum value, like if it is Trillion than divide your number by 10¹² and than divide it with 10⁹ and down to division with 1 or to decimal points if you need. if will be simple recursive sort of method.

Hope that help or let me know to give you complete source code for it.
