Where is BigDecimal currency converted?

[Ruth Hoffman]

Hello Developers:
I'm having a problem on my live eCommerce site where, when a user 
selects any locale other than English, the BigDecimal value of the order 
item's price is not being converted correctly to a string. For example a 
Big Decimal value of "10.000" is getting displayed as "10,00" and being 
passed back in the form as "10,00". I'd like this value to be "10.00" as 
it is when the locale is set to English. I've spent most of the morning 
trying to figure out where this is converted done in the code, but  with 
little success. Could someone who has worked on this please tell me 
where to start looking?

FYI - I tried replicating this on the 9.04 stable release demo site but 
screen rendering is really messed up so I can't seem to get to a place 
where I can create a final order to look and see what the values being 
passed back look like.

TIA
Ruth
