This Yet Another Web Calculator uses the Javascript
eval() function to evaluate whatever you put in the in
window. Any valid JavaScript code works, whether it's 1+3 or Math.pow(10,13)-1
(you can also leave off the
"Math.") or even navigator.userAgent
or even, in Netscape Navigator's implementation of Liveconnect,
java.lang.System.getProperty("java.version") (these examples
also show that expressions can appear as part of the URL "command
line"). WebCalc uses window.onerror() to catch errors. Click here for further help, which
will appear in the console window below. WebCalc can use JavaScript
"include" files; until I get around to properly documenting this, here's an example.
Feel free to reuse this little example, but please keep my name, email
and URL below intact. Thanks!
