The general rule that you should apply when determining which data type to use is set forth by John Walkenbach in Excel VBA Programming for Dummies: This means that different types use a different amount of bytes. These data types have different nominal allocation requirements.
VBA data types determine the way in which data is stored in the memory. The ability to determine the characteristics of the variables you create in VBA is probably the main reason why understanding VBA data types is important. One of the characteristics that you can determine is the VBA data type. You determine the name and characteristics of any variable you create. You can create variables in Visual Basic for Applications by declaring them. In other words, variables act as placeholders for values. You generally use variables to represent a particular value.

Module level variables are declared at the top of code modules with the Dim statement. Tired of Searching for VBA Code Examples? Try AutoMacro! Module Level Instead, you can declare Long variables at the module or global level. Variables declared with a procedure can only be used within that procedure. In the previous examples, we’ve declared the Long variable within a procedure. A Double can have up to 12 decimal places while Currency and Single can both have up to 4 decimal places.ĭeclare Long Variable at Module or Global Level The Single data type will round the decimal point slightly differently to the double and currency data type, so it is preferable to use double to single for accuracy.
