Unless I am misunderstanding the problem, I don't think you need the inner loop at all. You only need to iterate over the list of keys once.

If that doesn't produce the desired result, please clarify the problem.

Update: Here is a modified version of your code (which may be more clear than my reply above).

use strict; use warnings; my %hash_1 = ( 0.2 => '12', 0.4 => '13', 0.6 => '14', ); my %hash_2 = ( 0.2 => '19', 0.4 => '18', 0.6 => '20', ); foreach my $key ( sort { $a <=> $b } keys %hash_1 ) { my $diff_obs_perm = $hash_1{$key}-$hash_2{$key}; my $FDR = $hash_2{$key} / $hash_1{$key}; my $currentdeltaprint = join ("\t", $key, $hash_1{$key}, $hash_2{$key}, $diff_obs_perm, $FDR ); print "$currentdeltaprint\n"; }

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
