Trailing whitespace can be a bit tricky. Maybe something like:

c:\@Work\Perl\monks>perl -wMstrict -le
"for my $n (qw(
   0.12345 -0.12345  123456.12 -123456.12  123456.12345 -123456.12345
   )) {
   my ($left, $right) = (7, 5);
   my $s = sprintf qq{%${left}s.%-${right}s}, split m{[.]}xms, $n, 2;
   print qq{'$s'};
   }
"
'      0.12345'
'     -0.12345'
' 123456.12   '
'-123456.12   '
' 123456.12345'
'-123456.12345'
