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:
- Reduce time before GUI appears on load in some cases
- Add derived units without symbol (e.g. kg/m³) to completion
- Option to remember window position
- Only perform continuous conversion when convert tab is visible
- Increase default precision to 10
- Add "Copy result to clipboard" to Gnome shell search provider
- Fix unit conversion search entry losing focus
- Fix potential precision loss when performing multiple consecutive unit conversions
- Fix self-contained Linux binaries: change GUI binary name to qalculate (fixes install and update scripts), and fix check for updates at startup
- Add abhenry (abH), cP, cStoke, mTorr, dyn/cm², and kph (or kmph) units, add biot (Bi) name for abampere, and replace J/T with A/m² as unit for current density (libqalculate)
- Use B as abbreviation for byte instead of bel (dB is still used for decibel) (libqalculate)
- Group digits after decimal separator (in groups of three, when standard digit grouping is active) (libqalculate)
- Group hexadecimal digits (libqalculate)
- Add binary prefixes zebi and yobi (libqalculate)
- Do not use prefixes by default with most CGS units (libqalculate)
- Do not use “$”, “dollar”, and “dollars” for USD (and do not use “£” as symbol for GBP) and remove cent, if the symbol is also used by the local currency (libqalculate)
- Consider vectors as matrices with one column (column vector) in operations that expect a matrix (e.g. matrix multiplication) (libqalculate)
- Fix cot(pi/2), coth(pi/2×i), arccot(0), arcsch(0), and arcoth(0) (libqalculate)
- Fix conversion to ratio (libqalculate)
- Fix logarithmic y scale in plot (libqalculate)
- Minor bug fixes and feature improvements
