dc(1) and leading zeros?

I've got a shell script and I do some calculations with dc(1).

I need to have one number printed with leading zeros; I can't find an easy and straightforward way to do this with dc itself, but the manpage does mention:

Z
Pops a value off the stack, calculates the number of digits it has (or number of characters, if it
is a string) and pushes that number. The digit count for a number does not include any leading zeros, even if those appear to the right of the radix point.
Click to expand...

Which sort of implies there is an easy and straightforward way ...

I know there are a zillion-and-one method of accomplishing this, and I the script is running happily with one of them. I'm just curious ;)
 
Fedora Core (Yeah, it's what we use at work. I don't have a lot to say in this matter).

It's both GNU dc, so I sort of assumed it would be the same on FreeBSD ... I just checked and on FreeBSD it's indeed different:

Code: 
       Z      Pops  a  value off the stack, calculates the number of digits it
              has (or number of characters, if it is a string) and pushes that
              number.
