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).

    With a name like “Qalculate” I was expecting it to be Qt-based, but it’s actually GTK-based. Nonetheless, thanks for posting!

    Just to mention it…libqalculate also comes with CLI qalc tool which I use all the time, it’s a great calculator. And Plasma’s krunner uses libqalculate as back-end for their integrated calculator. I think anything that contains a “=” in krunner get send to libqalculate allowing things like =plot(x^2+2x-3 ; -10) in the krunner input.

    Edit: The function list is something worth having always a hand when doing calculations with krunner.

    This may be unremarkable to others, but I was really excited to see that Qalculate! can solve for x. I really miss my TI-89 graphing calculator and having something that can solve complex equations for me is comforting.

      No clue about the gtk frontend as I don’t use it but with the qalc shell tool you can use a 0d prefix:

      > 0d9
  9 = 9
> 0dA
  10 = 10
> 0dB
  11 = 11
> 0d10
  12 = 12
