Re^2: Round numbers?

Because I am new to Perl and don't understand it that much, can you please tell me how these lines interpret?

for my $n (@nra) {
   my $fmt = $n > 0.001 ? '%5.2g' : '%5.3g';
   printf qq{$fmt \n}, $n;
   }

It's like:

for my $n (@nra) {
    my $fmt=$n;
    if($n>0.001){
                    ?????  
                }
     else
                {
                     ??????
                }
     printf qq{$fmt \n}, $n;
    }

Thank you for your time!

No, like: `for my $n (@nra) { my $fmt; if ($n > 0.001){ $fmt = '%5.2g'; } else { $fmt = '%5.3g'; } printf qq{$fmt \n}, $n; }` [download] See Conditional Operator in perlop. Note that `$x = $y > $z ? 'foo' : 'bar';` is perhaps more clearly written as `$x = ($y > $z) ? 'foo' : 'bar';`	[reply] [d/l] [select]
