Version: (using KDE 4.0.1)
Installed from: SuSE RPMs
Currently, the operator ^ on krunner xor's numbers, instead of raising one to the power of the second. This maybe useful for programmers and other technical minded people, but normal/most people expect =2^4 to be 16, not 6.
Another related problem is that when typing ^ followed by a number, for example =2^4 it's written as =2⁴ (unless you press space before typing the number), and krunner doesn't recognize this at all.
Solved in KDE trunk.
^ now equals to pow.
and or xor for binary operations.
Thanks for the suggestion
