![]() Most unit converters stop at a long list of basic units and a bunch of common combinations, but not ConvertAll. OK, it's not a "calculator," yet this simple application is incredibly useful. Also, Qalculate! is more flexible with syntax errors, so you don't need to worry about closing all those parentheses: if there is no ambiguity, Qalculate! will give you the right answer.Īfter a long period on which the project seemed orphaned, it came back to life in 2016 and has been going strong since, with more than 10 versions in just one year. It's licensed under GPLv2 (with source code on GitHub) and offers versions for Linux and Windows, as well as a MacOS port. Have you heard of an exapascal pressure? I hadn't (the Sun's core stops at ~26 PPa), but Qalculate! has no problem understanding the meaning of 1 EPa. Its use of units is far more intuitive than SpeedCrunch's and it understands common prefixes without problem. It allows you to work with units, handle physical constants, create graphics, use complex numbers, matrices, and vectors, choose arbitrary precision, and more. The project offers a powerful library that can be used by other programs (the Plasma desktop can use it to perform calculations from krunner) and a graphical interface built on GTK3. Qalculate! (with the exclamation point) has a long and complex history. It works on Linux, Windows, and MacOS, and it's licensed under GPLv2 you can access its source code on Bitbucket. The list of available functions is really impressive. More options are available on the Configuration menu. With the F5 key, all results will turn into scientific notation ( 1.08e9 kilo meter / hour), while with F2 only numbers that are small enough or big enough will change. If a problem comes up that reminds me why I must have Qalculate, I’ll come back and try to build from source.It supports working with units and comes loaded with all kinds of functions.īy default, SpeedCrunch delivers its results in the international unit system, but units can be transformed with the "in" instruction.ģ*10^8 meter / second in kilo meter / hour So much time has gone by that I cannot remember the specific features of Qalculate that were so important to me at the time. I think I’m just going to switch to SpeedCrunch. In order for me to build from source, I’d need detailed step-by-step help because I tried already and got stuck. If someone doesn’t find that useful, as I do not, then both qalculate-kde and qalculate-gtk build pretty cleanly from source on 11.2. If a plasmoid with limited functionality is helpful, great: kde4-plasmoid-qalculate is available on the build service. I have no idea what OP’s requirements are I was just trying out qalculate to see if I liked it better than speedcrunch, noticed that neither of the GUI frontends were packaged for 11.2, and found this thread. Is a plasmoid, which is itself horribly inconvenient (for me, anyway!).Cannot be used outside of KDE4 (obviously).Does not have a fraction of the functionality of the KDE3 frontend.In any event, I was only speculating as to why the KDE frontend supplied by the author of qalculate is not packaged-I am neither the author nor the packager, so I don’t know for certain. The fact that there are KDE3 repositories on the build service is certainly true, though last I knew no one had been found to maintain them. KDE3 is no longer shipped with opensuse, per the release notes. After the operation, additional 8.5 MiB will be The following NEW packages are going to be installed: Retrieving repository ‘Updates for openSUSE 11.2-0’ metadata īuilding repository ‘Updates for openSUSE 11.2-0’ cache Retrieving repository ‘Packman’ metadata īuilding repository ‘Packman’ cache ![]() Should I leave it enabled? Change the priority?ĭoes the following look correct? I’m having a hard time seeing which repository Qalculate was installed from, based on this sudo zypper in qalculate People seem to advise against using 1-click installs. ![]() Which version do I install for openSUSE 11.2 64bit KDE? I’m thinking it must be this one:īut there are lots of very similar choices. ![]()
