Converting Numbers to Strings

You already know that you can use variables in your macros, and that there are two very basic types of variables: string variables (containing characters) and numeric variables (containing numeric values). You can quickly and easily convert a number into a string in your macros. This is the done with the Str() function. The way you use this function is as follows:

A = Str(B)

In this syntax, if B is equal to 5, then when completed, A will be " 5"; if B is -4, then A would be "-4". Notice the leading space when converting positive numbers. This may not provide satisfactory results for some subroutines. Instead, you should create a function that returns a stripped-down version of the string. The following function does just that:

Function ToNum(X as Variant) as String
    ToNum = Trim(Str(X))
End Function

The reason that the value passed to the VBA function (X) is defined as a Variant is that you can then pass any type of numeric value.

An alternative approach is to use the following variation of the function:

Function ToNum(X as Variant) as String
    ToNum = CStr(X)
End Function

Either approach will work just fine.

Using "Str" in the macro means it will error out if the cell reference you pass it contains a non-numeric value. eg aaa in the cell will result in #VALUE.
It is also unnecessary both the following options work fine without it.

Function ToNum(X As Variant) As String
ToNum = Trim(X)
End Function

And even just relying on defining ToNum as a string is enough to do the job
Function ToNum(X As Variant) As String
ToNum = X
End Function
