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).
GUI improvements:
- Currency flags.
- Context menu for conversion list, and middle click for adding unit to expression.
- Search entry for functions, units and variables.
- Improved convert to menu in unit manager.
- Workarounds for bugs in GTK+ themes
Changes from libqalculate:
- Improved interval arithmetic with dependent values (variables and function arguments). Most differentiable expressions do now return a properly narrow interval.
- Experimental limit() function.
- Two's complement representation for binary numbers.
- Improved currency titles.
- bitcmp() function.
- Allow all rational numbers for second argument of root().
- Fix segfault when prefix is set in some cases.
- Fix a^infinity when a > 1.
- Minor bug fixes.
