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:
- Option to specify number of displayed significant digits, instead of using precision
- Option, in menu, to open settings folder(s)
- Improve decision to automatically convert unchanged quantity with unit
- Fix number base subscripts in programming keypad, and fix updating of number bases before any calculation has occurrred
- Fix keyboard shortcut with copy followed by quit
- Fix initial selection and exclusion of optional arguments from output of insert function dialog
- Fix precision in Preset mode
