Maybe it is late, maybe I am tired, but what the fiddley-doo is up with this:

$ perl -e 'my $val = 8.95; printf("%d\n", int($val * 100));'
894

Or this for that matter:

$ perl -MPOSIX -e 'my $val = 8.95; printf("%d\n", POSIX::floor($val * 
+100));'
894

[download]

So in desperation:

$ perl -e 'my $val = 8.95; my $mval = $val * 100; printf("%d %d %f %d 
+%f\n", int($val * 100), $val * 100, $val * 100, $mval, $mval);'
894 894 895.000000 894 895.000000

It looks like maybe the %d in printf is rounding. But why does it round 895.000000 to 894?

What exactly is going on here?
