dime

Simple In-Memory database for currency conversion based on the eurofxref data.

Features

• The database is updated automatically every day.
• If there is no rate for a currency on the given date (e.g holiday), the latest known is used.
• There are no rates for weekends so the friday rate is always used if present.
