Hey Fake,

Is that really a pic of you?
It's kool, you look like the prisoner of Azkaban!

Nice to see people with a sense of humour.

 KOffice Integration?

Realy nice Tool!

What do you think about a funktion to export the formula + the result in a KFormula (and maybe OpenOffice)compatible syntax? [copy to clipboard]
Maybe you could simply use the same syntax as KFormula does in your app so its easier to use and it could get part of KFormula sometime.

 power user features

It does the same job as bc (or dc). Some features could make it more interesting than bc (for me :)
* a dialog for customizing the fonts (my parents have a bad sight) and the colors
* telling when an expression is valid or not *before* actually typing it would help a lot
* having tab completion for functions given the first letters

Font and color customization will come in version 0.4

I don't really understand what you mean by
"telling when an expression is valid or not before actually typing it". How can the program know the expression if you don't type it? Please elaborate.

Tab completion? Good idea, I'll put it in my TODO.

The expression being typed could be parsed on-the-fly (for each character typed) to tell if a valid result can be returned (numeric).

Another interesting feature would be a button to clear the line, like in eqchem (another kind of calculator, see http://www.kde-apps.org/content/show.php?content=14542 :).

When angles are in radians we should have:
sin pi = 0
probably your definition of pi is not precise enough

PS KCalc returns the correct result!

The new version 0.5 should solve such kind of precision problem.

Just wanted to thank the author. I've always used the python-interpreter for calculations before, but speedcrunch is more suitable. Keep it up!

tanks for this great application.
would love to see it integrated into kde.
speedcrunch is much better to use than kcalc

After version 0.6 (coming soon! with new interesting features), SpeedCrunch will be fully KDE-fied.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
