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'
Give a man a fish: <%-{-{-{-<

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
