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+ and CLI).
Changes:
- Persistent keypad option, which makes it possible to show the keypad and the history simultaneously
- Minimal window mode, which hides everything but the expression entry and, when not empty, the result
- Optional (disabled by default at compile time) internal help viewer using WebKitGTK
- Fix segfault during calculation of atan(acos(x)), atan(asin(x)), and asin(atan(x)) when angle unit is degrees or gradians (libqalculate)
- Fix order of prime factors (libqalculate)
- Fix immediate closing of plot window if qalc is started in non-interactive mode (persistent parameter added to plot() function) (libqalculate)
- Minor bug fixes and feature improvements
