## calculate total
my $total = 0;
foreach keys (%hash) {
$total += $hash{$_};
}
## create a new hash to an anonymous array
foreach keys (%hash) {
$percentage = ($hash{$_}/$total) * 100;
$browsertype{$_} = [$hash{$_}, $percentage];
}
## access
foreach keys (%browsertype) {
print "Value: $_: $browsertype{$_}[0]\n";
print "Percentage: $_: $browsertype{$_}[1]\n";
}
Untested though :)
