/**
* Definition from MSDN: encapsulates the CURRENCY data type used in
* Automation. CURRENCY is implemented as an 8-byte, two's-complement integer
* value scaled by 10,000. This gives a fixed-point number with 15 digits to the
* left of the decimal point and 4 digits to the right. The CURRENCY data type
* is extremely useful for calculations involving money, or for any fixed-point
* calculation where accuracy is important. It is one of the possible types for
* the VARIANT data type of Automation.
*
* for example :-
* If the absolute value of the fractional part is greater than 10,000, the
* appropriate adjustment is made to the units, as shown in the third of the
* following examples.
*
*
* Note that the units and fractional part are specified by signed long values.
* The fourth of the following examples shows what happens when the parameters
* have different signs.
*
*
* COleCurrency curA; // value: 0.0000
* curA.SetCurrency(4, 500); // value: 4.0500
* curA.SetCurrency(2, 11000); // value: 3.1000
* curA.SetCurrency(2, -50); // value: 1.9950
*
*
