Euro converter


Euro converter ( value ; fromCurrency ; toCurrency ) -> Function result

Parameter	Type	Description
value	Real	Value to convert
fromCurrency	String	Code of the currency in which the value is expressed
toCurrency	String	Code of the currency into which the value must be converted
Function result	Real	Converted value

Description

The Euro converter command converts any value from and to the different currencies belonging to “Euroland” and the Euro currency itself.

You can convert:

a national currency into Euros,
Euros into a national currency,
a national currency into another national currency. In this case, the conversion is calculated by the intermediary of the Euro, as specified in the European reglementation. For example, to convert Belgian francs to Deutschemarks, 4D will perform the following calculations: Belgian francs -> Euros -> Deutchemarks.

Pass the value to convert in the first parameter.
The second parameter indicates the Currency code in which value is expressed.
The third parameter indicates the Currency code into which value must be converted.

To specify a Currency code, 4D proposes the following predefined constants, placed in the “Euro Currencies” theme:

Constant	Type	Value
Austrian Schilling	String	ATS
Belgian Franc	String	BEF
Deutsche Mark	String	DEM
Euro	String	EUR
Finnish Markka	String	FIM
French Franc	String	FRF
Greek Drachma	String	GRD
Irish Pound	String	IEP
Italian Lira	String	ITL
Luxembourg Franc	String	LUF
Netherlands Guilder	String	NLG
Portuguese Escudo	String	PTE
Spanish Peseta	String	ESP

If necessary, 4D performs rounding automatically on conversion results and keeps 2 decimals —except for conversions to Italian Lires, Belgian Francs, Luxembourg Francs and Spanish Pesetas, for which 4D keeps 0 decimal (the result is an integer number).

The conversion rates between the Euro and the currencies of the 11 participating Member States are fixed:

Currency	Value for 1 Euro
Austrian Schilling	13.7603
Belgian Franc	40.3399
Deutschemark	1.95583
Finnish Markka	5.94573
French Franc	6.55957
Greek drachma	340.750
Irish Pound	0.787564
Italian Lire	1936.27
Luxembourg Franc	40.3399
Netherlands Guilder	2.20371
Portuguese Escudo	200.482
Spanish Peseta	166.386
