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:
- Ask (once) for correct interpretation of ambiguous implicit multiplication
- Immediately return memory on MR clicked if entire expression was unchanged (or empty)
- Fix segfault with very old GTK versions (~3.10) when opening unit edit dialog
- Improved simplification of radical expressions (libqalculate)
- Improved Im(), Re(), and arg() functions (libqalculate)
- Improved output of complex forms (other than the default rectangular) in exact mode (libqalculate)
- Immediately return memory on MR clicked if entire expression was unchanged (or empty) (libqalculate)
- Function for drill bit size conversion (libqalculate)
- Fixes for equations with complex inverse trigonometric and hyperbolic functions with no solution (libqalculate)
- Fixes for complex x^(ax)=b (libqalculate)
- Fixes for localization on Windows (libqalculate)
- Minor bug fixes and feature improvements
