The method GetCurrency returns an array of the language independent
parameters of a currency by its identifier. The method is similar to CCurrency::GetByID
except the fact that the GetCurrency result is cached. Therefore, the
repeated calls with the same currency identifier within the same page does not
incur extra queries to the database.
||The currency identifier.
Associated array with the following keys.
||The three character currency code.
||The number of currency units used by default to define the rate
of exchange (for example, if CYP 10 equal to USD 21.58, 10 is the number
of currency units).
||The default rate of exchange. (One of currencies within a site
must equal to 1. Such currency is called a base currency. Other
currencies are defined relative to the base currency.)
||The date that the record was last modified.
