VBA Data Types and Limits Currency
Example
Dim Value As Currency
A Currency is a signed 64 bit floating point data type similar to a Double, but scaled by 10,000 to give greater precision to the 4 digits to the right of the decimal point. A Currency variable can store values from -922,337,203,685,477.5808 to 922,337,203,685,477.5807, giving it the largest capacity of any intrinsic type in a 32 bit application. As the name of the data type implies, it is considered best practice to use this data type when representing monetary calculations as the scaling helps to avoid rounding errors.
The casting function to convert to a Currency is CCur().
