I use this new version, gcalctool 5.31.1 in Lucid (10.04) and I love.

Nice colors, very functional.

There is already a ppa to use the 5.31.x build in ubuntu lucid. It comes with most of the features that are coming in Maverick's gcalctool. Paste these lines into the termnial.

sudo add-apt-repository ppa:robert-ancell/gcalctool
sudo apt-get update && sudo apt-get upgrade

It "looks" nice but, until gcalc has rpn mode it's useless to me.

They're really doing great things with that top right corner where the buttons used to be. Shuttleworth is really living up to his promises!

Yes, but how fast is it?

If I wanted a bajillion features I'd just use octave or bc - when I need to add two numbers, I don't want to have to wait five seconds. On a command-line I can beat Windows out with dc, but if I'm stuck with a GUI, it's quicker to do math mentally than to open a calculator program in Linux.

Another vote for RPN, please.
Like the programmer mode, though.

Until the calc program can do everything my ti-89 can do, no thanks.

Harumph! Until gcalc can equal the speed and coolness of the sliderule I carry in my pocket protector, no thanks!

RPN all the way! Please try to add this. With a very long buffer

Judy's TenKey is my fav. I could take a report that included text and numbers, paste it into TenKey and it'd strip the text and give the sum of all the numbers. Also a tape type display in which changing a number at the top would cause a cascade of changes to occur based on the new result.

Just try Judy's Tenkey and do a legal imitation of that. Used it since the 90's and have never found a better one... works with WINE by the way.

I really dislike this calculator. It no longer has the simplest, yet the most useful features: you cannot resize the window, and you lost the history. For me this is a pitiful regression.

This calculator is ridiculous...no memory? What a JOKE. I guess I'll have to copy and paste...never thought I'd have to do to that with a calculator.

I agree
Before I was very easy for me to do a simple negative int to an hexadecimal form change a bit and copy/paste the result ...
Now i can do a simple negativ int => 32bit hex .

Where are the memories????? All that new glitz has no value to me. How can I load the one from 10.04 back into 10.10???

HTML code?
