InfoPath Dev

I am using Infopath 2010 browser form

I have a field that has a number in it and I want to be able to show it spelled out

i.e. $1,000 would be One Thousand Dollars

Anyone have any ideas?  I could also do it in SharePoint but haven't been able to figure out how to do it there either.

Thanks

At present, the only feasible way I know of doing this is to use code.  I guess it could be done with some complex rule logic, but I've never attempted that.

Here is a thread on the code approach:
