Qalculate! 0.9.6

Qalculate! is a multi-purpose desktop calculator for GNU/Linux. Qalculate! project is small and simple to use but with much power and versatility underneath.
Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface (KDE or GTK+).
Main features:
- Redesigned GUI with history view in the main window
- Display of as-you-type expression parsing and function hints
- Enhanced completion
- Scaling of result display to vertically fit the window
- Nicer history listing
- Enhanced result display with much nicer parentheses
- Meta modes
- 67 new units: bel (B) and neper (Np), information units such as bit and byte, many convenience units (km/h, deciliter, etc), and more.
- Binary prefixes
- Some new variables and functions
- Fixed help display in new yelp
- Fixed compile with cln-1.1.10
- Fixed regressions in simplification
- Fixed f(x) return type analysis (ex. log(x) represents a real number if x represents a positive). This was by accident unused.
- ...and many more bug fixes and enhancements...
Enhancements:
- Use Lambert W to solve more equations and avoid infinite loop when solving some equations
- More data on elements
- Fix simplification of (1-1/x)^3 and similar
- Fix clumsy mistakes in with prefixes leading to crashes
- Fix parsing of unit expressions (when converting) such as W/(m K)
- Add more exact values for sin() and cos() and avoid floating point underflow by, in approximate mode, checking against the value of pi
- Always input decimal separator sign on keypad separator press
- New units: typographic units, pouce, pied du roi, grams of TNT and tons of TNT
- New functions: lambertW(), addDays(), addMonths(), addYear(), addTime(), isNumber(), isReal(), isRational(), isInteger(), representsNumber(), representsReal(), representsRational(), representsInteger()
- New variable: omega constant
- Other minor fixes and enhancements
