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 continuously display result while editing expression
  • Option to specify number of displayed significant digits, instead of using precision
  • New functions: tripleProduct(), multilimit()
  • Improve decision to automatically convert unchanged quantity with unit
  • Improve ability to abort matrix functions
  • Add plot() function example, and support expression in y=f(x) format
  • Place "approx." on same line as value (instead of as equals sign) in qalc
  • Display "aborted" for long aborted result in qalc
  • Updated French translation
  • Fix case conversion of µ to M and similar
  • Fix segfault with very large integer raised by very large integer
  • Fix wrong output of converted unit with non-numerical exponent in some cases (e.g. ft^x converted to m without expansion)
  • Fix "sqrt(x-1/x) sqrt(1-1/x)-x=0" when approximation is not exact
  • Fix clear using Ctrl L when input line is not empty
  • Minor bug fixes and feature enhancements
