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:
- Ask (once) for the correct interpretation of dots, when comma is decimal separator
- Improve simplification of logical expressions (boolean algebra) and add boolean assumptions for unknown variables
- Add nand and nor operators and spelled out version of logical not operator ("not"), and interpret bitwise operators as logical in some cases
- New functions for inverse cumulative distributions: chisqdistinv(), fdistinv(), normdistinv(), and tdistinv()
- Add inverse incomplete beta function, betaincinv(), and improve betainc() (now returns regularized incomplete beta function)
- newtonsolve() and secantsolve() functions for solving equations using Newton's or secant method
- Do not return dot product when multiplication operator is used with vectors (use "." or dot() function instead)
- Russian and German translations
- Fix cumulative t-distribution for X < 0
- Customizable text color and button padding (qalculate-gtk)
- Option to keep the main window above other windows (qalculate-gtk)
- Activate first (or selected) completion item using Tab key (qalculate-gtk)
- Fix custom keyboard shortcuts without modifier (qalculate-gtk)
- Minor bug fixes and feature improvements
