Hello,

Using v151 fresh install.

How reproduce this issue:

- Add a product_general with price 0.367, no taxes.
- No attributes, discounts or prices modifications, nothing.

I my example I put 80 units in the cart.

shopping_cart page is showing 29,60 instead 29,36.

But checkout is showing 29,36.

In currencies I have euro as default with 2 decimal places and a value of 1.00000000 and the currencies conversion ratio is 1.00000000

Thank you.
