title: Magento 3 decimals when ordering products in backend
body: <p>When creating a product in magento catalog we have 3 decimals but when they are added to a order they become 2 and lose the 3rd number, leaving the price rounding up to a wrong number and adding a cent to the price. </p>
  
  <p>For example 350.00 EUR becomes 350.01 EUR when added to cart then this shows up every where. </p>
  
  <p>The VAT is 21 percent and we tried changing how VAT works (per item, per line, per cart) but it works on some producs but not all. </p>
  
  <p>We atleast need to find how to make 3 decimals when creating an order on the product list, this way we could fix some of the problem.</p>
  
  <p>Preview: 
  Need 3 decimals in the custom price input:
