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 (including changes from libqalculate):
- Add calculate-as-you-type result to history after idle time
- Negate, sum, and "LAST x" RPN buttons, keyboard shortcuts for RPN stack manipulation, and various other RPN improvements
- Option to use binary prefixes by default for information units and "b?" syntax for conversion to optimal prefix (e.g. 8192 bits to b?byte = 1 kibibyte)
- Bijective base-26 support (including bijective() function)
- Option to use 'j' as default symbol for the imaginary unit (placed in front of the imaginary part)
- Angle/phasor notation for complex numbers
- poisson() function
- Fix segfault when saving mode/settings (on exit) if history is empty
- Fix for steradian conversion
- Fix and improve integral of abs(f(x))
- Minor bug fixes and feature improvements
