It does! Here is a proposed patch. We could add a separate radix control later if you like.

One detail that I'm undecided about is whether to remove the more obscure control escapes \f, \a, \v, \e and \d, on the grounds that they are less likely to be used as actual characters and that users may prefer to see them as numbers instead. C, and most languages inheriting them from C, lack \e or \d; \f and \a are rare today, and \v is an anachronism.

Actually, 'integer' in 'integer radix' plays the part of adjective!
