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+ and CLI).
Changes:
- Temperature calculation modes (absolute, relative, hybrid)
- Allow prefixes, with full name, without units (e.g. kilo = 10^3)
- Extended and improved simplified Chinese translation
- Save handle vector function argument property
- Fix never ending loop when calculating []*[]
- Save chain mode setting (qalculate-gtk)
- Handle SIGTERM signal (qalculate-gtk)
- System tray improvements (qalculate-gtk)
- Add convert to mixed units to result context menu (qalculate-gtk)
- Minor bug fixes and feature improvements
