Retail prices are quoted gross. Taking 20% off a gross price is the classic
error: the VAT in a 120.00 gross price is 20.00, not 24.00.
The net is gross x 10000 / (10000 + rate), and the tax is whatever is left, so
net and tax always add back to exactly the gross with no stray penny.
1.0.1 adds tests; behaviour unchanged.
