Public bug reported:
Binary package hint: x11-apps
Under Ubuntu 8.04.1, running the version in x11-apps_7.3+1_i386.deb, the
calculator program xcalc has problems with the order of operations.
To recreate this bug, run "xcalc" from the command line, then type
"2*2^2+2=". The result displayed should be "10", but instead it is "12".
Note that "2+2*2^2=", "2^2*2+2=", "(2*2^2)+2=", and "2*(2^2)+2=" each
give the correct result.
My guess is that the program has problems when it must close two levels
of implicit grouping at once. In effect, it treats the problematic input
above as if it were "2*(2^2+2)=". This interpretation is consistent with
other examples that I've tried.
