Sadly, Raspbian is lacking a package for this software. There’s a web interface and a command-line version. That’s all SI units, all units that are accepted by SI as well as most units of the imperial and US customary systems (and many more). Insect is a high precision scientific calculator with full support for physical units. When running this example, the software uses only 15MB of RAM. There’s the command-line frontend, the GNOME frontend, and the common files, all installed with the command: There’s a few packages for Raspbian to install on your system.

Some distinctive features are auto-completion of functions and variables, a formula book, syntax highlighting. It features a syntax-highlighted scrollable display and is designed to be fully used via keyboard. SpeedCrunch is a high-precision scientific calculator. You get the latest release, version 0.12, but there hasn’t been a new release since late 2016. The program uses around 21MB of RAM, so it won’t cause any memory issues.Ĭlick for full size imageFor some strange reason, I wasn’t expecting SpeedCrunch to be present in Raspbian repositories. I didn’t run into any problems running Qalculate! on the RPI4. It meets everyday needs too, with things like currency conversion and percent calculation. It’s easy to use, but at the same time it’s packed with useful features often reserved for complicated math packages. Qalculate! is one of my favourite calculator programs. We’re missing out on a lot of development, so you might want to try compiling the source code. That’s an old version released back in December 2018. There’s a package available for Raspbian offering version 2.8.2. Fortunately, there’s far more sophisticated software available for the RPI4 which offers the ability to process complex mathematical functions, plot 2D and 3D graphs, and much more.Ĭlick for full size imageQalculate! is a powerful and easy to use calculator. There’s user defined functions, and 3 different notation modes: Algebraic, Reverse Polish, and Formula Entry.īut I need more functionality than galculator offers.

The image shows the program in its basic mode, but there’s also a scientific mode, and a paper mode, the latter is a formula entry mode. This program is unmaintained.Īs calculators go, galculator is a basic affair designed for simple calculations. But there hasn’t been a new version since September 2015.
