Can any one explain why the following is happening? Or is perl rounding incorrectly? (example): 

my $y = 40.88050;
$y = sprintf "%.3f", $y;
my $x = 41.78050;
$x = sprintf "%.3f", $x;
print "$y \n $x\n";

Results are:

40.880
41.781

As far as my wife, 10-year-old, and I can figure this is wrong - they should both end in a 0 or a 1 depending on if even or odd rounding is the rule.
C is doing the exact opposite, it comes up with:

40.881
41.780
