Calcoo

Calcoo is a scientific calculator designed to provide maximum usability. Its features bitmapped button labels and display digits to improve readability, no double-function buttons, undo/redo buttons, copy/paste interaction with the clipboard, both RPN and algebraic modes, two memory registers with displays, displays for Y, Z, and T registers, and tick marks to separate thousands. Calcoo is written in C using the GTK+ widget library (v.2.2+).

            Your calculator program was the first package I've installed by hand from the source code. It worked! Better than that I get my old HP28 back with a gorgeous GTK skin on it. Thanx.
