Hello Marc,

Hmm, that route is likely going the path to sprintf: First a flag to
select among %e, %f, %g. Then an optional width. Then a flag to select
whether to fill with spaces or with zeroes.
If you go that route, it's better to start with full sprintf and define
a particular "precision" that would mean "as many digits as needed to
guarantee that the result can be unambiguously read back in".
