in reply to Help with this statement

I believe your problem is the non-transative nature of the perl || and 'or' operators. in this case you are asking if it is equal to 456 or just 453. 453 of course is never 0 and therefore will be true. Hence printing something. to fix this just add. 
if ($value == 456 || $value == 453){
print something;
}
else 
{
print nothing;
}

That should clear things up.

    I couldn't resist this as a TIMTOWTDI :) 
    unless (abs($value - 454.5) - 1.5) {
  print something;
}
else 
{
  print nothing;
}

      just as an alternative, it can also be written as: 
      my $value = 444;

if ($value == 456) { print "something"; }
elsif ($value == 453) { print "something"; }
else { print "nothing"; }
