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:
- Improve resolution and sizing of flag images
- Do nothing when Enter is pressed if expression is empty
- Restrict use of reciprocal in unit conversion, e.g. invert in "5m/s to s/m" (= 0.2 s/m) but not in "500/lb to g" (= 1.1/g) (libqalculate)
- New mHg unit (allows use with prefixes other than milli) (libqalculate)
- Always display abbreviated unit name (symbol) with abbreviated prefix (when unit only has short name) (libqalculate)
- Minor improvements to automatic unit conversion (libqalculate)
- Fix display of (1 + f(x))/n (libqalculate)
- Minor bug fixes and feature improvements
