- the ultimate desktop calculator
Qalculate! is a multi-purpose cross-platform desktop calculator. It is simple to use but provides power and versatility normally reserved for complicated math packages, as well as useful tools for everyday needs (such as currency conversion and percent calculation). Features include a large library of customizable functions, unit calculations and conversion, physical constants, symbolic calculations (including integrals and equations), arbitrary precision, uncertainty propagation, interval arithmetic, plotting, and a user-friendly interface (GTK+ and CLI).
Qalculate! is free software, licensed under the GNU Public License v2 (or later).

.: 2020-06-26 :. Qalculate! is now avilable at FlathubThe flatpak package (for Linux) has now finally been added to Flathub (flathub.org/apps/details/io.github.Qalculate). To install the package follow the link or use the command "flatpak install https://flathub.org/repo/appstream/io.github.Qalculate.flatpakref".
Flatpak users are adviced to replace previous installations. Note however that the app-id has changed. In order to preserve configuration and data you will have to manually copy the files (from ~/.var/app/io.github.qalculate.Qalculate to ~/.var/app/io.github.Qalculate).
For Windows users, Qalculate! was recently added to the Windows Package Manager (winget) community repository, making updates easier.
