Re: rounding off all members of a hash

That way is fine. I might have mapped instead:

my %rounded_stats = map {
    $_ => sprintf '%.2f', $stats{$_}
} keys %stats;

That eliminates some temporary lexical variables which aren't really needed. (They could be eliminated in the explicit loop, too.)

Another way to do the actual rounding is to use Math::Round. The nearest() function can round to a whatever acuracy you want. This does the same as the sprintf() version, except that the results are numbers, so you don't get trailing '0' characters in the output: `my %rounded_stats = map { $_ => nearest(0.01, $stats{$_}) } keys %stats;` [download]	[reply] [d/l]

It seemed long. I need to think about using map more. thanks	[reply]
