Because neither 2.1345 nor 22.1345 can be represented exactly in floating point, and the errors are in the opposite direction: In [4]: repr(22.1345) Out[4]: '22.134499999999999' In [5]: repr(2.1345) Out[5]: '2.1345000000000001' Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
