Description

TCurrencyField is the field class used by TDataset when it needs to manage currency-valued data.(TField.Datatype equals ftCurrency). It simply sets some Tfield properties to be able to work with currency data.

It should never be necessary to create an instance of TCurrencyField manually, a field of this class will be instantiated automatically for each currency field when a dataset is opened.
