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:
- Option to change the default currency
- Customizable digit group size and separator
- Improve interpretation of function expressions with x, y, or z in object names (e.g. "x year"), or within quotation marks
- Ellipsize long titles in completion list
- Fix replace expression with result
- Fix opening of menu in menubar when completion list is visible
- Show error when function or variable disabled by "--disable-insecure" is used (libqalculate)
- Fix infinite loop during factorization on Windows (libqalculate)
- Minor bug fixes and feature enhancements
