Qalculate! is a multi-purpose cross-platform desktop calculator. It is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface (GTK+ and CLI).
The main focus of version 2.1 is consistent handling of roots of negative numbers and equation solving enhancements.
List of main changes:
- Equation solving enhancements.
- root() and cbrt() now always returns the real root (e.g. cbrt(-8)=-2), while fractional powers return the principal root ((-8)^(1/3)=1+1,73i).
- Enhanced simplification and factorization
- More than 100 additional currencies (using mycurrency.net)
- Fix automatic prefix for negative values.
- Fix optimal unit conversion for cbrt(L) and similar.
- Fix wrong partial calculation of square root in exact mode in some cases
- Minor bug fixes and feature enhancements.
