Hi,

Im selling products in big quantities but with very small unit prices, so the total order needs only 2 decimal, but I understand that it's legaly mandatory to display the unit price in invoice, and so then I need to display it with 6 decimal (if not unit price x quantity will not be equal to total price displayed)

so, How can I set the unit price to be displayed with a different decimal number (6 decimals) from all others prices (2 decimals) ?

Thanks

I see,

didnt think about that, great!
