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:
- Do not change result color when window loses focus
- Do not add separator line if history duplicate was prevented
- Do not convert empty expression
- Fix memory leak when updating result display
- Fix close to systrem tray for 32-bit (and potentially 64-bit) Windows binaries and remove icon before exit
- Fix small dot visible when expression is empty with some default fonts
- Fix segfault if result widget is not realized when first drawing
- Fix Unicode handling when ellipsizing during saving of long result
- Fix "Customize completion…" item in expression popup menu
- 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)
