n3toy: I have a hash where the values are all numerical. Is there a quick way to sum all the hash values? GrandFather: my $total; $total += $_ for values %hash; Lawliet: $sum += $hash{$_} foreach keys %hash; tye: my $count= map( (1)x$_, values %hash ); Lawliet forgot there was a values keyword! davido: use List::Util qw(sum); my $total = sum( values %hash );
