I want to round off all the values in a given hash to 2 decimal places. I do not want to mess with the original, given hash. This is what I came up with:
use strict;
use warnings;
use diagnostics;
use Data::Dumper::Simple;
my %stats = (
'stdev' => '42.5371995604396',
'pct_10' => 0,
'variance' => '668.660986666667',
'sterr' => '17.3657390016697',
'median' => '-130.925',
'pct_90' => '94.4',
'average' => '131.503333333333'
);
print Dumper(%stats);
my %rounded_stats = ();
foreach my $stat (keys %stats){
#print "$stat $stats{$stat}\n";
my $round = sprintf("%.2f", $stats{$stat});
$rounded_stats{$stat} = $round;
}
print Dumper(%stats);
print Dumper(%rounded_stats);
Is this the best way? Any advice or tips?
