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:

  • Use formatted output in status display
  • Do not add separator line if history duplicate was prevented
  • Case-insensitive history search
  • Use different font sizes for expressions, messages, and results in history
  • Ellipsize long completion names list
  • Insert minus instead of executing RPN operation, on key press, when last character is e
  • Updated Tab key behaviour, e.g. cycle through completion items on subsequent tab key presses, and traverse items if tab key is unbound
  • Fix action (e.g. conversion, factorization) on uncalculated expression
  • Fix scaling of result (when it does not fit)
  • Show warning when log() is used with a single argument, and always show second argument of log()
  • Option to plot real and imaginary parts separately (enabled by default)
  • Polar plot style
  • Ask the user for the desired sinc() variant (unnormalized or normalized)
  • Support for binary-coded decimals (BCD)
  • Show names with underscore capitalized and with underscore removed (with some exceptions)
  • Variable spacing of x values in plot (unless step size is used) (libqalculate)
  • Updated plot() function with arguments for specification of plot options (in any order after the third argument) (libqalculate)
  • Additional information units (libqalculate)
  • Units for volumetric flow rate (libqalculate)
  • Tradtional numbers (e.g. dozen, score) (libqalculate)
  • Make names with a single character followed by digits case-sensitive with suffix by default (libqalculate)
  • Accept more than two arguments in gcd() and lcm() (libqalculate)
  • Interpret a single vector argument as a list of arguments if function requires more than one argument (libqalculate)
  • Fix limit of floor(), ceil(), and trunc() (libqalculate)
  • Fix plotting of derivatives and integrals (libqalculate)
  • Fix randpoisson() (libqalculate)
  • Fix reactivation of object, after object that caused deactivation is removed (libqalculate)
  • Minor bug fixes and feature enhancements
