    Re: What CN Calculators Are On Your LapTop DeskTop?

    Thanks for uploading those, Greg.

    Since I know that there's a really great range of Internet skills among NavList members, I wanted to point out that four of the five files that Greg has attached to this message are stand-alone calculators. They are "web pages" in format and style, but they are local files which can sit on your computer and function without an Internet connection. They do their calculations entirely locally using Javascript. So if you "right-click" or "option-click" or whatever is the equivalent on your device on any of the ".html" files that are in Greg's message, you can save them locally on your computer and run them whenever you want, even a thousand miles from the nearest Internet connection. Also, if you are interested in seeing how they work, you can use the "view source" option in your browser (try right-clicking on the tool while it's open) and you can see the actual Javascript code that makes it go. Even if you don't understand programming, you can probably figure out the trig steps and thereby verify for yourself that the tool is doing something useful, and you can also check to see if it's doing any extra steps that you don't want.
