Issue description

Hello,

I have in my shop some items with 4 decimals prices (sometime 0.001). The minimum quantity of these kind of product is very large so I am always sure than the gran_total can be a 2 decimals number.

But the payment failed because of the paypal service check if the gran total price == the sum of all the items prices. These prices are set to 0 because of the formatToPrice function.

I wondering how I can fix that and if it is correct to change the items price to 4 decimals number ?

Thanks
