Releases: Qalculate/qalculate-gtk
Qalculate! version 2.6.2 (GUI)
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, interval arithmetic, plotting, and a user-friendly interface (GTK+ and CLI).
Changes:
- Polar and exponential complex forms (changed with mode or with "to" operator/command)
- Fix f(x)+a=a (e.g. x+1=1, which returned false/zero).
- Fix ln(-i).
- Fix automatic unit conversion in RPN mode
- Allow conversion of the current result using standalone "to" expression (e.g. type "to m" to convert current result to meter) in GUI.
- Option to disable automatic conversion to local currency (when optimal conversion activated).
- Minor bug fixes.

- Automatic conversion to local currency (in "optimal" conversion mode).
- Calculate each vector element (and each extra argument) separately in many functions (e.g. sin(5, 2, 3) = [-0.95892427, 0.90929743, 0.14112001]).
