+any expanded token) with your choice of character (defaulting to @samp{0}) to
+your choice of number of places (defaults to @samp{2}).  This works not only
+on Arabic numerals, but on any expanded list of tokens passed to it.  This
+makes it suitable for, among other things, counters of all kinds.")
