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 automatically calculate the current selection, in tooltip
- Option to calculate the current selection, once in history
- Toggle fraction format action for custom keyboard shortcuts and keypad buttons
- Fix copy unformatted ASCII without units when unit is placed before quantity
- Fix solve() function with replace() function as first argument (fixes solve2() function) (libqalculate)
- Fix "where" operator using (in)equality in variable (libqalculate)
- Return x=ae^(ir) (with r instead of n) for abs(x)=x (libqalculate)
- Minor bug fixes and feature enhancements
