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:
- Show error when function or variable disabled by "--disable-insecure" is used
- New completion method with matches selectable from numbered list

- Improve interpretation of function expressions with x, y, or z in object names (e.g. "x year"), or within quotation marks
- Fix compilation with -fsanitize=undefined
- Fix make check with --disable-insecure
- Fix infinite loop during factorization on Windows
- Fix crash after factorization or in RPN mode, with calculate-as-you-type enabled
