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:
- Updated insert function dialog layout
- Add description field to variables and units dialogs
- Add customizable keyboard shortcut for insert result
- Insert "smart parentheses" with right parenthesis key if expression has selection or text cursor is at start
- Add language option to configuration file

- Fix norm() and magnitude(), and add second argument, p, to norm() function (libqalculate)
- New text operators: dot, cross, comb, and perm (libqalculate)
- Add support for ^^ as XOR operator (libqalculate)
- Fixes and improvements in multisolve() function (libqalculate)
- Always return exact result in base() function, in exact mode (libqalculate)
- Improve parsing of functions without parentheses (libqalculate)
- Do not try to load data objects from global definitions dir if data set is local (libqalculate)
- Interpret "±" at end of expression as "±0" (libqalculate)
- Add support for QALCULATE_USER_DIR environment variable and always check for "user" directory on Windows (libqalculate)
