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).
This version includes a critical bug fix for the display of negative numbers with scientific notation.
Changes:
- Fix display of negative numbers with scientific notation
- Fix BTC, BYN, and BYR exchange rates (libqalculate)
- Fix exchange rates update time (libqalculate)
- Fix parsing of negative power in function arguments without parenthesis (libqalculate)
- Add arcsin, arccos, arsinh, arcosh, etc. as names for inverse trigonometric and hyperbolic functions (libqalculate)
- Interpret sin^-1, cos^-1, etc. as inverse functions (arcsin, arccos, etc.) (libqalculate)
- Add deftorad() and totient() functions (libqalculate)
