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, symbolic calculations (including integrals and equations), arbitrary precision, uncertainty propagation, interval arithmetic, plotting, and a user-friendly interface (Gtk, Qt, and CLI).

Changes:

  • Apply dual approximation/fraction to calculate as you type result, as regular result but with length restriction
  • Add option to add/edit comment to history context menu, and save comments in result on exit
  • Add "Search by Date" (also shows the date of the expression) to history context menu
  • Option to automatically group digits in input
  • Option, in menu, to open settings folder(s)
