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:

If you are using an earlier version (Excel 2003 or earlier), this tip may not work for you. For a version of this tip written specifically for earlier versions of Excel, click here:
Function ToNum(X as Variant) as String
ToNum = Trim(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.

IMHO, creating a function like ToNum that simply returns the result of another function is dumb.

As noted later in the Tip, A = Str(B) is not the correct way to convert a numeric data type into a String data type; use A = CStr(B) instead. CStr(...) converts any data type into a String data type. Str(...) returns a string "representation" of a number.
