Weird math...

[Bill Stephenson]

I've got a script that takes numbers similar to those below and then rounds
them and adds them together using code similar to what is below.


    #!/usr/bin/perl -w

    use strict;

    my $item_1 = "1.655";

    my $item_2 = "1.755";

    my $rnd_1 = (sprintf qq~%.2f~, $item_1);

    my $rnd_2 = (sprintf qq~%.2f~, $item_2);

    print "$rnd_1, $rnd_2";


The code above prints this result (system 10.1.5, perl 5.6.0):

    1.66, 1.75

But shouldn't it be:

    1.66, 1.76

or:

    1.65, 1.75

I'm no math wizard, so if someone could please take the time and tell what
I'm missing here I would very much appreciate it!
