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:
- Chain syntax (e.g. 1+2*3=(1+2)*3=6)
- Make all currency codes (except CUP and KGS) case insensitive
- Fixes for floating point format output
- Fix segfault on factorization in qalc
- Fix saving of local data objects
- Fix BYN exchange rate url
- Redesigned expression, status, and result widgets (qalculate-gtk)
- Chain mode (GUI) (qalculate-gtk)
- Configurable calculate-as-you-type add to history delay (qalculate-gtk)
- Option to use a system tray icon (hides the application when the main window is closed) on Windows (qalculate-gtk)
- Improved completion (qalculate-gtk)
- Support for qalc commands in GUI (expression is interpreted as command if it begins with '/') (qalculate-gtk)
- Support for reading expressions and commands from file in GUI (as in qalc, using command line option -f/--file) (qalculate-gtk)
- Use arrow instead of "to" by default (qalculate-gtk)
- French GUI translation (qalculate-gtk)
- Fix segfault when closing 32-bit Windows binaries (qalculate-gtk)
