Prices aren’t real numbers. They aren’t even fractional. They are integers with a fixed point, which is an entirely different domain.

- laumars 6y agoYou put quantities on shipping lists, not prices. Prices go on the receipt. They would be integers rather than real numbers. edit: you've now edited your post to repeat a lot of what I put above. Though I doubt intentional (probably a race condition of us both posting at the same time). Anyhow, I'll keep what I posted as it's still relevant.
- jfkebwjsbx 6y agoYeah sorry, I added more because leaving it at the first sentence could be misunderstood. It is true that in home shopping lists there aren’t prices. I was thinking more about company ones (like parts).
- laumars 6y agoEither way your point is valid :)
