calc.pl is a download-and-use terminal calculator.
Yes, there is a lot of calculators for linux on the web.
Once I was looking for something simple, fast to use, something where you can see the history of operations (tape calculator like gtapecalc), with minimum use of mouse, I didnot succeed. Most of the calculators are GUI - means that functions you must use the mouse or learn some shortcuts.
Non-GUIs look too complicated (like Easy Stack Calculator) or look too simple (like lcalc).
There are "linux-built-in" things like bc (arbitrary precision calculator language) or octave, but their purpose is a little bit different from what I wanted.
Here are some key features of "calc pl":
· No instalation, just download.
· Runs in terminal = fast copy-paste and/or remote operation.
· Fast quit with Ctrl-c
· Line editing, acces to previously issued commands
· Help command from prompt. Just type "help"
· Standard functions (goniometric, logs) and some special functions
· Default operations (repeating operations modes)
What's New in This Release:
· A bug in the goniometric functions was fixed.
· The ability to use decimal commas was added along with a few fancy features, including automatic terminal-tab name, saving history on Ctrl-C, and better help.
