            Best calculator
            Best calculator for Linux right here. Love the RPN feature, as I

            use HP calculators.

            What can be said, its a scientific calculator. It uses GTK2.
            It works. I use it. Sorry I can't get excited over a calculator, but if xcalc doesn't meet your needs, then try this. I'm happy with it. I'm just writting this so its known that this program works. And that someone uses it :-)
