And we tripped over a shopping cart issue where rounding meant that
buying 10 items ended up costing a penny more than buying the ten
individually, inevitably someone spotted it and complained (yes, about
a one penny difference!)
The difference happens depending on whether you do the calculation
(item cost + vat) x 10
or (item cost x 10)+vat
Tax man is happy with either as long as you are consistent.
As for rounding down - oh bugger I'd just persuaded my script to round
both figures up consistently!
