But again, the root 'bug' is in floating point, which cannot exactly represent the numbers you give. See What Every Computer Scientist Should Know About Floating-Point Arithmetic. `c:\@Work\Perl>perl -wMstrict -le "for my $f (5.245, 9.325) { print sprintf '%.20f', $f; } " 5.24500000000000010000 9.32499999999999930000` [download] Update: Slight cosmetic change to code example.
