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).
This version primarily includes a large number of stability and reliability improvements, thanks to automatic testing of hundreds of thousands of randomly generated mathematical expressions.
Changes (including changes from libqalculate):
- Fix convert button.
- Propagation of uncertainty using variance formula (if interval arithmetic is disabled).
- Improved and extended physical constants, now defined in relation to each other (e.g. RK = (μ0c)/(2α)).
- Natural, atomic, and Planck units.
- Reciprocal unit conversion (e.g. 5 m/s = 0.2 s/m, 60 mpg = 0.039 L/km).
- Updated elements and planets data sets.
- +/- syntax for non-numeric values.
- raid() function for RAID capacity calculation.
- UTC+/-hh[:mm] and CET time zone conversion (using "to").
- Minor bug fixes and feature improvements.
