Version: (using KDE 4.0.1) Installed from: SuSE RPMs OS: Linux 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
