This module formats currencys as if they were in the country the
currency is used in. It would be much more useful if one could also
supply a country.
Example:
4000 GBP in the UK, is written as £4,000.00
4000 GBP in Germany, is written as £4.000,00
Number and symbol formatting need to be separate, or one needs to be
able to supply a country, which may default to the country the currency
belongs to.
