Where subtotal equals (quantity * price - discount). So I subtract 1224.97 - 489.98 to get 734.99, the remaining subtotal for that line_item. The problem is that when I get into Shopify's dashboard, I see the amount as 734.98 (there's a one-cent difference). My guess is that the discount_allocations amount is being rounded. My question is: How can I then get the exact value using only the data provided in the APIs.
