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:
- Allow multiple "to"-conversions in one expression (e.g. "5 m/s to hex to ft to h = 0xE6AF.1E*ft∕h)
- Support specification of number of bits for hexadecimal "to" conversion (4 to hex16 = 0004)
- Improvements and fixes for sexagesimal numbers and time format
- Support for +, -, (, ) Unicode superscripts, and N-Ary Summation symbol
- Syntax highlighting using colours in qalc
- Enable Unicode by default in qalc (on platforms other than Windows)
- Improved display of unit expressions
- Fix segfault when parsing an expression that contains a prefix with more than one letter followed by a unit and an exponent without exponentiation operator
- Fix use of equals sign in qalc command line arguments (e.g. "qalc --base=16")
- Support for automatic updates of self-contained binaries
- Option to clear history on exit (qalculate-gtk)
- Fix removal of history items, and move to top, when calculate-as-you-type is activated (qalculate-gtk)
- Reduce the height of the result widget (qalculate-gtk)
- Hide tooltip after keypad button click (qalculate-gtk)
- Check for updates menu item (qalculate-gtk)
- Slovenian translation (qalculate-gtk)
- Fixes for the Gnome shell search provider (qalculate-gtk)
- Minor bug fixes and feature improvements
