Determining If a Number is Odd or Even

A common programming task is validating user input. Often, your macro may need to determine if a number entered by a user is odd or even. For instance, suppose you wrote your own macro that asked the user what worksheet number they wanted to process. If your macro had to process odd and even worksheets differently, then you need to figure out if the number the user provided was odd or even. The technique for this is relatively simple, as shown here:

Even = (UserNum Mod 2) - 1

After execution of this line, Even will be True (-1) if UserNum was even, or False (0) if UserNum was odd.
