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, Qt, and CLI).
Changes:
- Option to disable cursor blinking
- Set ans variable to solution(s) of equation (as if solve() function were used)
- a(i) and a[i] syntax (the latter with support for functions) for element in vector (libqalculate)
- New function: factor() (libqalculate)
- Use hours or minutes as default unit for conversion to time unit of expression with time format but no units (e.g. "0:00:12 to s") (libqalculate)
- Always use four digits for year in date (e.g. "0064-07-18" instead of "64-07-18"), and support input of date using DD-MM-YYYY format (libqalculate)
- Fix solving of x^4-4x^3+10x^2-12x+1=0, and similar, in exact mode (libqalculate)
- Fix rounding in 1/# conversion to integer (e.g. "1/2 to 0.99") (libqalculate)
- Fix unability to find approximate solutions to some high degree equations (e.g. "x⁴ − 4x³ + 10x² − 12x = −1") (libqalculate)
- Fix automatic variable detection in select() (libqalculate)
- Minor bug fixes and feature enhancements
