This Script was written by Joe Homs
Here's a useful, advanced, calculator. It'll basically do everything. There's nothing to configure. Just cut and paste what pops up when you grab the script. Make sure to grab EVERYTHING! It's a lot of text. Get it all or error messages will come up all over the place.
Please note: This script is being offered in simple text format. When you click to Grab the Script, the text should display. Internet Explorer and AOL users may get a blank page or the script may run and produce the effect. If this happens, choose SAVE AS from the FILE menu and save the blank or compiled page.
