It gets worse than that. You have to be careful of the order you perform
certain operations on the items you're pricing. Things like; do you
apply VAT/sales tax on the total of an order, or on each item.

These details will be part of the tax codes or the various regions
you're dealing with. I think they'd also mention the precision of the
calculations needed (e.g. calculate to 1/10th of a cent)
