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:
- Unit and data set creation/editing
- Complete variable and functions editing
- Percentage calculation dialog
- Periodic table
- Show result in expression status tooltip (calculate-as-you-type)
- Horizontal toolbar with added units and plot buttons
- Favorite functions, units, and variables (shown in toolbar menus)
- Fix segfault with Qt 6.2
- New functions: linearfit(), quadraticfit(), cubicfit(), ramlatency(), parallel() (libqalculate)
- Improved and extended parallel operator (|| is interpreted as parallel if units are used) (libqalculate)
- Merge inv() and inverse() functions (libqalculate)
- Allow nested subfunctions (libqalculate)
- Solve x^(x^(-a))=b (libqalculate)
- Fix pearson() and spearman() (libqalculate)
- Fix asin(x)+bcos(x)=c (libqalculate)
- Fix display of incompletely solved equation with dual approximation in some cases (libqalculate)
- Many feature improvements and bug fixes (see the git log for more details)
