1239.499.. => 1239.50
2. Phase 2 – Dual Currency
This phase allows dual currency trading. The base currency – the currency in which all values are
stored internally - will be Euros. payment in Punt is permitted.
1.1. Rounding errors
Internal monetary values are stored in cents (whole numbers).
Payment in Punt may result in rounding errors in the cash taken, for example:
€ = £0.787564
Item A costs €10 = £7.87564 => £7.88
After 10 single sales, actual cash taken = £78.80
Reconverted => €100.06
Internal product sales = €100
Discrepancy = 6¢
It is not proposed to track and store this discrepancy internally in the POS.
Similar small discrepancies can also occur because change and gratuities from Punt tender must be
calculated in a way that ensures that the Punt values add up exactly (for the customer).
