At its simplest, a Variant can contain either numeric or string information. A behaves as a number when you use it in a numeric context and as a string when use it in a string context. That is, if you’re working with data that looks like VBScript assumes that it is numbers and does the thing that is most appropriate numbers. Similarly, if you’re working with data that can only be string data, treats it as string data. Of course, you can always make numbers behave as by enclosing them in quotation marks (” “).
