Fixed Exchange rate calculation method

[magj]

Hi

Sorry if it's asked before, I'm googling it (and searching it in this forum) for hours but I couldn't get it to work

I have a base currency call it AAA that is my shop's base currency , I want to have a fixed exchange rate to USD that I'll enter it daily or so.

1 USD = 40000 AAA

then it is : 0.000025
When I Set AAA to 1 and USD to 0.000025 , it is rounded to 0.00003
How should I enter this exchange rate?
When I Set it in reverse it's not working (AAA > 40000 and USD to 1)

Virtuemart 2.0.22a , Joomla 2.5.11 - PHP 5.3
Any help would be greatly appreciated
Regards

Did you try to dig code that responsible for rounding exchange rate?

Thanks for your reply,
No, I couldn't find where is that exactly.

You could do a text search 'currency_exchange_rate' in VM files.
