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:
- Conversion to any type of expression (e.g. "1000 BTC to million USD")
- Use current status of limit implicit multiplication setting during parsing of conversion expression
- New SI prefixes (R, r, Q, q)
- New units: ounce force (ozf), rack unit (U)
- Use standard form (sorting) for polynomials
- Improve consistency of behaviour when global units are replaced
- More consistent addition of units to expression without units for unit conversion
- Improvements and fixes for arg() and atan2() functions
- Fix interpretation of Myr (megayear) and Gyr (gigayear)
- Fix milli- and centimeter of water units
- Fix genvector() with for negative step size or expression as step size/number of steps
- Fix randuniform() function
- Fix automatic/dual fraction format after conversion (e.g. "8 to score")
- Fix inconsistently displayed parsing of "7d 5h" and similar
