Qalculate! is a multi-purpose cross-platform desktop calculator. It is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface (GTK+ and CLI).
The main focus of version 2.3 is enhanced integration capabilities and basic solving of differential equations. Qalculate! should be much more usable for calculation of integrals now, even though it is still far from perfect.
There is also some important plotting fixes, as well as many minor bug fixes and feature enhancements. For details see the changelog for libqalculate and qalculate-gtk.
