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).
Changes:
- Updated physical constants (CODATA 2018)
- bitrot() function for bit rotation
- Bitwise XOR, mod and rem operators, % as modulo, // and \ operators for integer division
- Change order of operations for logical and bitwise operators to better match C operator precedence
- Improved support for functions, variables and units with input base > 10
- Programming mode
- Unicode support in char() and code()
- Simplification and factorization improvements
- RPN syntax improvements
- Recognize "factor" and "expand" commands at the beginning expressions
- For vector + scalar, add scalar to all components
- uptime variable
