in reply to weird print behavior

"perldoc -q .999999" will explain this better than I could. You're experiencing a non-Perl-specific problem with finite precision for floating point numbers.

Using printf "%.2f\n", $i will give you what you expect.

    Well, that does make a certain amount of sense. However, why does this only show up sometimes? In the loop I get the problem, but when I do 
    printf("%.14f\n", (6.8 + .1));
