DESCRIPTION

calc is a scientific calculator. Buttons can be selected and clicked, but it also includes button-bindings for typing directly into the window. Backspace can be used to undo a single-button numerical entry. calc also includes a set of constants, and memory for adding more. It also has a menu of other applications, including mortage, and function sampling and plotting.
