> How do account 3 items that cost 1/3$ each (e.g. if in a bundle)? You never account for fractional discrete items, it makes no sense. A bundle is one product, and a split bundle is another. For products sold by weight or volume, it's usually handled with a unit price, and a fractional quantity. That way the continuous values can be rounded but money that is accounted for needs not be.
