-3 - 2 = --5?

there are some errors with handling negative numbers. any word on whether or not it will be inproved? I see it was updated on June 20, so maybe it will.

good work thus far :wink:

Beautiful looking calculator with equally pleasing skins.

Only complain is that the choosed skin doesnt save after re-opening the widget. For ex, I choose red theme(awesome!), close the widget, open it again and its back to the default black shiny skin.

Hope this will be improved?

simple is good for use thanks

Useful but the problem i have is when i change the skin colour it always defaults back to it's original one.

Is there a fix for this?

Commas are not good. Every calculator in the word uses a decimal point.

How come the decimal looks like a ,?
It gets kinda confusing for 90 divided by 100
and get 0 ,9
It's easier to understand if it is just .9 or 0.9

Good Widget but there seems to be a error with the decimal point it has been replaced with a comma

I'll make the skin persistent and will look further in the '-' problem. Do you have a formula in mind where the problem occurs ?

By p01 , # Jun 22, 2006 10:13:19 AM

I choose one skin, but the next time I open the calculator it doesn't appear. Is possible to save the skin I want during sessions of the opera browser?

In addition, I don't know what's the matter with the minus sign, because sometimes it appears double, and when I write '-' directly from the keyboard it doesn't appears at all.

What do you mean by inputed numbers ? do you press they digits on your keyboard or click them on the widget ?

This widget uses a keyup event, that *might* explain the loss of a digit/operator when typing fast.

I've tried the calculations reported by marek.roesel. They work with the v1.0.1

This calculator does not work properly. It misses inputed numbers and freezes. Totally unusable for anything other than simple addition of two numbers. I am running a high end machine so I know the problem is not on my end.

Widget fixed. And since you seemed to enjoy the designs, a nice and clean skin has been added.

The widget is diabolical!
It is a nice looking thing but not a calculator at all.
I tried to calculate 10 - 2 x sqrt(5)
10 - 2 x ........... gives eight!
Well, it is a SIMPLE calculator.
Let's try sqrt(5) ....... it works
x +/- 2 = ............. gives -2
= again ................. gives -4.7... which is correct
+ 10 .................... gives 14.7

Well, I tried a simple one:
-2 + 5 = ................ -25

So once you enter a negative number, you cannot enter any operation and regardless to what you press, you are entering new digits of the negative number.

So far I liked Opera, but in case Opera Software is able produce and publish such a ... well, neve mind. Author of this widget should be fired or paid as a comedy writer but not as a programmer any more.

But the design is sweet... :-)

By SteveW , # Apr 17, 2006 2:44:42 PM

Redmon, just click on download and Opera will do the rest. All you have to do is to choose Want to keep this widgets? Yes? No? It's that easy!

By Saigonian , # Apr 13, 2006 5:42:49 PM

Please help me! I don't know the process of installation this widgets. How it works?

By Redmon , # Apr 5, 2006 4:17:47 PM

Just restart or reinstall the widget, this will work.

By DandS , # Feb 7, 2006 7:33:40 PM

This is a known Opera Widgets bug which shows up form time to time. It seems to not be Widget specific.

To see the full Widget, restart Opera, and it should be there.

By geirp , # Feb 7, 2006 2:51:15 PM

strange, only half the calculate shows up on my computer. i can only get to the bottom half of the calculate by mousewheel scrolling down. and whenever i try to mouseclick any of the buttons on the bottom half, it will disappear and the top half will show again.
