Thanks a lot! My comment about '#' was that the description of '#' suggested that it would only change things when the precision is 0 (which wasn't true).

I'd like something like this (with a hypothetical %q):
(format "%.3q" 3) ⇒ "3"
(format "%.3q" 3.00) ⇒ "3"
(format "%.3q" 3.30) ⇒ "3.3"
(format "%.3q" 3.05) ⇒ "3.05"
(format "%.3q" 3.352) ⇒ "3.35"
(format "%.3q" 3100000) ⇒ "3100000"
This is in fact just the same as 'g', except for the last entry (%g produces "3.1e+06"). Is this achievable?
Thanks!
Clément.
