i am still having problems with this................. say ; 

my $numbers = ('0.12', '0.35','1.34');

[download]
the code below perfectly calculates the greatest difference between two numbers, but i can't get it to return only the two numbers between whcih the difference lies. Any ideas how I could do this? thanks again. e.g. output 
the diff between 0.35 and 1.34 is 0.99.

  for ($i = 2; $i < @numbers; $i++)   {

       if (defined ($numbers[$i]) && defined ($numbers [$i-1]))   {

          $d = abs ($numbers [$i] - $numbers [$i-1]);
          $d =~ s/-//g;
          $diff = $d if $diff < $d;

          @diff_val = "$numbers[$i]\t$numbers[$i-1]\n";
          @diff_val = split ('', $testing);
          push (@d, $d, $diff_val[0], $diff_val[1]);
   }



 }

print "Greatest difference in the first sample is $diff\n";
