Country codes are short alphabetic or numeric geographical codes (geocodes) developed to represent countries and dependent areas, for use in data processing and communications. Several different systems have been developed to do this. The term country code frequently refers to ISO 3166-1 alpha-2 or international dialing codes, the E.164 country calling codes.
The CFA franc is the name of two currencies, the West African CFA franc, used in eight West African countries, and the Central African CFA franc, used in six Central African countries. Although separate, the two CFA franc currencies have always been at parity and are effectively interchangeable. The ISO currency codes are XAF for the Central African CFA franc and XOF for the West African CFA franc. On 22 December 2019, it was announced that the West African currency would be replaced by an independent currency to be called Eco.
The European Currency Unit was a unit of account used by the European Economic Community and composed of a basket of member country currencies. The ECU came in to operation on 13 March 1979, and was assigned the ISO 4217 code. The ECU replaced the European Unit of Account (EUA) at parity in 1979, and it was later replaced by the euro (EUR) at parity on 1 January 1999.
ISO 4217 is a standard published by International Organization for Standardization (ISO) that defines alpha codes and numeric codes for the representation of currencies and provides information about the relationships between individual currencies and their minor units. This data is published in three tables:
Listed below is a of historical exchange rates relative to the U.S. dollar, at present the most widely traded currency in the world. An exchange rate represents the value of one currency in another. An exchange rate between two currencies fluctuates over time. The value of a currency relative to a third currency may be obtained by dividing one U.S. dollar rate by another. For example, if there are ¥120 to the dollar and €1.2 to the dollar then the number of yen per euro is 120/1.2 = 100.
The ouguiya, at one time spelled "ougiya", is the currency of Mauritania. Each ouguiya constitutes five khoums. As such it is one of two circulating currencies, along with the Malagasy ariary, whose division units are not based on a power of ten.
The International Union of Railways is an international rail transport industry body.
A currency pair is the dyadic quotation of the relative value of a currency unit against the unit of another currency in the foreign exchange market. The currency that is used as the reference is called the counter currency, quote currency, or currency and the currency that is quoted in relation is called the base currency or transaction currency.
The neutral unit of construction or neutral unit of currency is a private currency used by the airline industry, to record fare calculation information. A set of exchange rates is issued by the International Air Transport Association (IATA) every month. The ticket component prices are converted from the original currency and recorded on the airline ticket.
Wagon numbers are key data for railway operations. They enable a railway wagon or coach to be positively identified and form a common language between railway operators, infrastructure companies and the state authorities. The system of wagon numbering has been laid down by the International Union of Railways and is similar to that used for the locomotives and multiple units. Vehicle numbering is now governed by the Intergovernmental Organisation for International Carriage by Rail and in Technical Specifications for Interoperability (TSI) of the European Union.
The European Unit of Account (EUA) was a unit of account most notably used in the European Communities from 1975 to 1979, when it was replaced at parity by the European Currency Unit, in turn replaced at parity in 1999 by the euro.
