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).
This version primarily includes a large number of stability and reliability improvements, thanks to automatic testing of hundreds of thousands of randomly generated mathematical expressions.
Changes:
- Equation solved and improved simplification for expressions with trigonometric functions.
- General improvements to simplification and equation solving.
- Improved factorization.
- New magnitude(), entrywise() and hadamard() functions, and new n variable (unknown integer).
- Parse |x| and ||x|| as abs(x) and magnitude(x).
- Use kilo as prefix for gram if automatic prefix is off.
- Many bug fixes and minor feature improvements.
