CY union (wtypes.h)

  • Article

A currency number stored as an 8-byte, two's complement integer, scaled by 10,000 to give a fixed-point number with 15 digits to the left of the decimal point and 4 digits to the right. This IDispatch::GetTypeInfo representation provides a range of 922337203685477.5807 to -922337203685477.5808.

The CURRENCY data type is useful for calculations involving money, or for any fixed-point calculation where accuracy is particularly important.
