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:
- Customizable digit group size and separator
- Option to enable/disable check for new versions
- Optional compact variant of parsed expression in history
- Highlight unmatched parenthesis (with red color)
- New default adaptive calculate-as-you-type delay (without delay in most cases)
- Improve decision to not do calculate-as-you-type or not show result of it
- "Approximation" caption changed to "Approximation and Fractions"
- New functions: reshape(), circshift(), replacePart() (libqalculate)
- Functions mergevectors() and area() renamed to slice() and part() (libqalculate)
- v[i, ...]=... syntax for assignment of part of matrix/vector variable (libqalculate)
- Improve language handling for functions, units, and variables (libqalculate)
- Limit the range of supported arguments in bessely, besselj, binomial, and igamma functions (to avoid segfault and very slow unabortable calculations) (libqalculate)
- Do not try to calculate exact result with automatic approximation for expressions with iterative functions (libqalculate)
- Fix handling of single quotation marks (libqalculate)
- Minor bug fixes and feature enhancements
