in reply to Can I pad a number with leading spaces rather than leading 0's

The output should be right-justified (padded with spaces) automatically.

To be more explicit: if you want the output to fit a field four spaces wide, e.g.
$ 123.00
$  12.00
$   1.00

Then you would want to
printf("\$%7.2f\n", $output);

    Oops, I missed the formatting of my results list (multiple spaces are ignored yadda yadda yadda) but you nailed it. I am looking for the all $'s to line up on the left and all the decimal places to line up on the right.

    sprintf("\$%08.2f", $price) formats the way I want to but I don't want to see the 0's.

    sprintf("\$%8.2f", $price) seems to forget about the padding up front.

      Works fine for me: 
      #!perl
$price = 16.50;
$formatted = sprintf("\$%8.2f", $price);
print "Price is $price, formatted price is $formatted.\n";
__END__

Price is 16.5, formatted price is $   16.50.

      Please clarify what you mean by "seems to forget." You seem to be saying that the spaces don't appear. Hmmmm ... just a thought ... are you using this to print to a web page, i.e., in HTML? You know, extra spaces don't appear in HTML unless you surround them with pre tags or similar formatting mechanisms.

        Thanx to everyone who responded, you guys nailed it! It was an html problem not a perl problem.

        I am now hanging my head in shame and getting several lashes with a wet noodle.
