- 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

FYI: I Just made the KDE version of Qalculate! into a FreeBSD port. It should be in the ports system for all in a few days, you can find it in math/qalculate-kde. If you can't wait go here: http://www.freebsd.org/cgi/query-pr.cgi?pr=90424

Thanks for the cool progie Niklas

This is a best calculator even i seen!
I use 0.9.0 version and wish this things:
- on kde startup i wish to start Qalculate hidden in tray, not actual window.
- ability to popup main window from tray and hide in tray by key combination
- ability to represent numbers as 0x0feff (for HEX), 0b0011101010 (for BIN)

- Version 0.9.3.1 fixes session management
- Hide in tray with key combination for closing window or Escape (in 0.9.3.1). If Qalculate! is already running the qalculate-kde will show and activate the window, so you can assign a key combination to the Qalculate! menu item.
- The third wish will have to wait for the next release of libqalculate.

Definitively!

Definitively the best calculator of the Free World! ;-)

Just one thing that I'd like to put on the wishlist: It would be better if we could change the number base of the display and of the expressions in a single dialog. When you want to change both bases, it's rather complicate.

Keep on the good work!

Big programs like Openoffice and Firefox get the press, but the true stars of the Free Software world are applications like Qalculate: free, Free, insanely elegant and with a communicative developer. It's this sort of thing thing that prevents even over-hyped environments like MacOSX from ever feeling anything other than cynical and alien.

The only feature that I might like is an easier in-place currency converter, which I think it used to have (ie: 10 USD = X GBP).
