# Currency

Currency configuration and price presentation.

Currency configuration determines how monetary values are represented and displayed. Confirm whether the deployment supports one base currency, multiple display currencies, or conversion rates.

## Monetary data

Store and calculate money using the precision and representation defined by the application/database. Avoid binary floating-point arithmetic for financial calculations. Keep the currency code alongside amounts and define rounding rules consistently across product display, cart, tax, shipping, payment, refunds, and order records.

## Conversion

If exchange-rate conversion is supported, document the rate source, update cadence, rounding strategy, and whether orders snapshot the rate at purchase time. Do not silently recalculate historical order totals when rates change.

## Verification

Inspect currency entities, configuration services, price/tax calculation code, and migrations. Confirm supported ISO currency codes and decimal precision from the implementation.
