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:
- Add option to show both parsed and entered expression (or only one) in history
- Add option to clear expression history
- Do not add duplicate results to history
- Improved result copying, with proper html format and ASCII option
- Do not replace *, -, / with Unicode operators if cursor is within quotation marks (apply same principles on paste)
- Improve window focus retrieval method on Windows
- Improve appearance of icons with display scaling (with Qt 5)
- Use non-breaking narrow space as digit separator in reasonably short numbers, and between quantity and unit (libqalculate)
- Update value of austronomical unit (libqalculate)
- Fix segfault (when compiled with -D_GLIBCXX_ASSERTIONS) with local digit grouping when separator is empty (e.g. with ignore locale) (libqalculate)
- Fix freezes and crashes with extrememly large vectors and matrices (libqalculate)
- Fix segfault (when compiled with -D_GLIBCXX_ASSERTIONS) in matrix multiplication (libqalculate)
- Minor feature improvements and bug fixes (see the git log for more details)
