Code: Sub IntegerExample () Dim k As Integer End Sub. Follow the below steps to see the example of a VBA Integer data type. Such functions are called user-defined functions. As we said, an integer can only hold whole numbers, not any fractional numbers. Therefore, in VBA, we use syntax to specify the parameters and data type while defining the function. We can also generate whole numbers using other VBA functions VBA Functions VBA functions serve the primary purpose to carry out specific calculations and to return a value. Example #3 – Generate Whole Random Number It will produce the same number repeatedly when we execute the code. Therefore, to get the same random number, again and again, we need to pass the argument as zero. So, for a generic function (along the lines of your code) to check if a Collection key is valid, you can use: Function HasKey (coll As Collection, strKey As String) As Boolean Dim var As Variant On Error Resume Next var coll (strKey) HasKey (Err.Number 0) Err. Example #2 – Get the Same Random Number Every TimeĪs we have seen in the previous example e, the “RND” function reproduces the result every time we execute the code. Since “RND” is a volatile function in nature, it reproduces different results every time you execute the code. Click on “OK” and run once more to see the result.
