I picked up a utility called printf (written by Chris Torek) which does
just what you describe, and does it quite well. It even does roman numeral
conversions. I believe it came across one of the comp.sources groups. Here
is an excerpt from the man page:

NAME
     printf - formatted output at shell command level

SYNOPSIS
     printf format-string [ arg1 ] [ arg2 ] ...

DESCRIPTION
     Printf duplicates  (as  far  as  possible)  the  standard  C
     library  routine  of  the  same  name,  at the shell command
     level.  It is similar to echo, except that  it  formats  its
     arguments  according  to  conversion specifications given in
     the format-string before writing them to the  standard  out-
     put.   For  a thorough explanation of format specifications,
     see printf(3s).

     For the sake of perversity,  printf  implements  one  format
     conversion  not supported by the standard printf subroutine:
     the %r and %R conversions, which  print  integers  as  Roman
     numerals.   The  first  format  produces  lowercase, and the
     second uppercase.
