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:

  • More robust and consistent default language detection and option to change language on Windows
  • Use Unicode symbol for minus in scientific e notation
  • Option to change symbols used for output of digits 10 and 11 in duodecimal numbers (use A and B as default digits)
  • Fixes for output of scientific notation using number bases other than decimal
  • Do not automatically by default set prefix higher than kilo for meter, gram, higher than 1 (no prefix) for second and litre, or lower than 1 for byte and bit (libqalculate)
  • Do not use recently introduced SI prefixes (R, Q, r, q) automatically by default (libqalculate)
  • Do not set automatic prefix if resulting multiplier is less than 1 or greater than 1000, with some exceptions (e.g. km) (libqalculate)
  • Default prefix unit property (use for gram, and few other units, instead of hard coded value) (libqalculate)
  • Allow the same variable left and right of the equals sign (e.g. var=var+2), in variable assignment without colon, if the variable exists and the previous value is known (libqalculate)
  • Do not show multiplier if exactly 1, in HTML output of scientific notation (libqalculate)
  • Prefer Nm (torque) over J when the result is a vector with three components (libqalculate)
  • Add "amp" abbreviation to ampere unit, and "thou" name for 1/1000 in (mil) (libqalculate)
  • Fix unit order for Nm and Ws (libqalculate)
  • Fix conversion from ounce (interpreted as fluid ounce) to litre with prefix (libqalculate)
  • Fix automatic reactivation of global object after deletion of conflicting object (libqalculate)
  • Fix parsing of scientific e notation when the number is extremely large and exponentiation fails because of floating point overflow (libqalculate)
  • Fix prefix selection in denominator when multiplier is higher than the value of the largest prefix (libqalculate)
  • Fix segfault in multisolve() (libqalculate)
  • Minor bug fixes and feature enhancements
