Hello Marc, > In a future version, I may add a flag to select between %e, %f, and %g.
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".
