A Percent Key needs to be added

Scientific Calulator by Anshugiri needs to be upgraded for OPERA 9.51
In addition a Percent Key needs to be added. The ^ Key does not function
and could be deleted.

cos(90) isn't equal to 0, but to 6.12e-17 by your calc.
degrees ofcourse...

How about a 10-key function calculator with an on-screen tape??

Actually this is extremely handy for windows users, seeing as how the windows calculator won't crunch radicals. It looks nice, its intuitive, and i like it. Job well done!!!!

gr8 job done............

can you make a widget by which mouseover event would genrate the ip address, location and the coordinates of the hyperlink..........

}

function hostipfox_disable() {
}

function hostipfox_init() {
if('__hostipfox__FillInHTMLTooltip' in window) return;
const prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefService).getBranch(null);

var originalFillInHTMLTooltip = window.FillInHTMLTooltip;
window.__hostipfox__FillInHTMLTooltip = originalFillInHTMLTooltip;

const dnsService = Components.classes['@mozilla.org/network/dns-service;1'].getService(Components.interfaces.nsIDNSService)

const nsISupportsString = ('nsISupportsWString' in Components.interfaces) ? Components.interfaces.nsISupportsWString : Components.interfaces.nsISupportsString;

window.FillInHTMLTooltip = function(elem)
{
var retval = false;

if (!elem ||
elem.namespaceURI == 'http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul')

Yeah... This was a good widget until I realized you couldn't use the number pad... BOOOOOO!

It should be possible to use the keyboard (and number pad)!
The display should be higher to allow display of previously entered numbers and operators.

Its close to usefull, windows oen calculator is quite anoying, id like to be able to use the num keyboard, don't knwo is thats a posibility

By RyomaNagare, # Jul 18, 2006 2:28:52 PM

I'm afraid "all the functions" is a bit of an exaggeration. No 10log, no hyperbolic sin, cos and tan, no inverse goniometry, no factorial... A usability handicap is that you have to click the digits with your mouse, rather than typing them with the numeric keypad.

Works well enough, but the usefulness, considering Windows' own calculator (I don't know if Mac and Linux have their own built-in ones, though), is questionable.
