Is the output unambiguous? Or would something like "decimal 2 is 10 in base 2" be better?

We have

  # convert this to a number using the given base.  If negative, add "-" as
  # the first character.
  #
  public as_string(base u32) String : character_encodings

in stdlib. Did you see this?

[simonvonhackewitz]

no 🙈

It doesn't work for 0 in base 999999 but I guess this is rarely needed

[michaellilltokiwa]

For base 999999 you would first need 999999 symbols. So no this is useless.

I know, I just thought it would be a nice (but probably useless) optimization, because 0 is the same in every base.
