Currently a bit limited, unfortunately printf's `%a` specifier is absolutely unreadable. So we add `hex` and `octal` with `0x` and `0` prefixes respectively, and also take a number but currently only allow 16 and 8. The output is truncated to integer, so scale values other than 0 are invalid and 0 is implied. The docs mention this may change.
