Hello kind Monks,

I am trying code a regular expression which will capture an "unsigned fixed decimal" value, preserving the original formatting. Here is what I'm trying to do: 

my $decimal = qr(\d*\.?\d+);
$_ = "0.12";
if ( m{(?<value> $decimal)}x ) {
   say "$_  $+{value}";
}

$_ = ".12";
if ( m{(?<value> $decimal)}x ) {
   say "$_ $+{value}";
}

$_ = "12.";
if ( m{(?<value> $decimal)}x ) {
   say "$_ $+{value}";
}

$_ = "12";
if ( m{(?<value> $decimal)}x ) {
   say "$_ $+{value}";
}

When I run this I get the following: 
0.12  0.12
.12 .12
12. 12
12 12

But the third line, I am not preserving the trailing decimal place, although the values should be equal.

Can anyone point out how I could change my "qr" so that it "works" for the third line?
