Hallo 

In expenses I need to get the product price with 4 decimals.

I followed the advices in this other post, but still when I select a product I get its price rounded at 2 decimals, i.e.:
- "cost per kilometer" = 0.5174
- once entered it becomes 0.5200

Amounts are computated using the rounded value, but I need them using the correct value.

How can I manage to get that?
