A strange thing has cropped up in my code. Here's the relevant snippet, with some debugging added:

my $val=0;
for (@rows) {
  if (/([\d.]+)/) {
    $val += $1;
    warn "<LI>Added $1 from $_ and set it to $val\n";
  }
}

The row values are mostly dollar-sign formatted, as you can see from the sample output. It gets funky at one particular spot:

I can guess that perl is setting the match in the regular expression as a float, because of the decimal place, but what cause it to suddenly decide that 6257.65 plus 33.40 is 6291.04999999999??

Any workarounds welcome, too, although the actual code is not as simple as the example above.
