calc is an interactive calculator which provides for easy large numeric calculations, but which also can be easily programmed for difficult or long calculations.
It can accept a command line argument, in which case it executes that single command and exits. Otherwise, it enters interactive mode. In this mode, it accepts commands one at a time, processes them, and displays the answers. In the simplest case, commands are simply expressions which are evaluated.
This is free and open source software.
