We already have such a feature. For example, (format "%09x" 257) returns "000000101", which is 257 hexadecimal, expressed using leading zeros as n= eeded=20 so that at least 9 digits are used. Once Emacs supports bignums, the same= =20 feature can print 40-hex-digit SHA-1 checksums by using (format "%040x" n= ).
