The module is currently only able to convert euro in currencies available at c:Data:ECB euro foreign exchange reference rates.tab and c:Data:Xe.com exchange rates.tab.

The function rate returns the number of 1 unit of the currency given as "source" in the currency given as "target" as the raw value calculated from available numbers. If "verbose" is set, the module throws an error if no conversion rate is available.

The function revisionTime takes "source", "target" and "verbose" and returns the date of the last update for the rate.

The function convert takes "source", "target" and "verbose" and additionally "amount". It converts the number given in "amount" in the "source" currency into the "target" currency with rounded digits.
