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:
- New functions: bernoulli(), erfi(), fresnels(), fresnelc()
- Improved zeta(), with exact values for negative and even integers, support for all real values, and optional second argument for calculation of Hurwitz zeta
- Support for complex numbers in Ei(), li(), Si(), Ci(), Shi(), and Chi()
- Support for all branches and complex numbers in lambertw()
- Extended argument support in Li()
- Add base units (or local currency) for unit conversion when units are missing in original expression (e.g. 5 to ft = 5 m to ft)
- Belarusian ruble (BYN)
- Improvements and fixes for integrals
- Fix crash when used in Cantor (caused by conflict with Poppler library)
- Minor bug fixes and feature improvements
