A more generic definition applying to all currency denominations would be:

 - **Main currency**: for the whole unit currency part left of the decimal point
 - **Fractional currency**: for the part to the right of the decimal point usually measured in 1/100 of the main unit (at least in modern times).

For more information, please see [Wikipedia - Currency: Control and production][1]:

> Each currency typically has a main
> currency unit (the U.S. dollar, for
> example, or the euro) and a fractional
> currency, often valued at 1⁄100 of the
> main currency [...]
