Currency rates in Codat are implemented as the multiple of foreign currency units to each base currency unit.

Where the currency rate is provided by the underlying accounting platform, it will be available from Codat with the same precision (up to a maximum of 9 decimal places).

For accounting platforms which do not provide an explicit currency rate, it is calculated as baseCurrency / foreignCurrency and will be returned to 9 decimal places.
