@EricPostpischil I suppose you mean something like
2.225073858507201...e-308. True, yet that supposes that the
printf()
is good enough to get the ultra precise conversion right and that
double
is binary64. If we assume those, then
%.800g
would have been more than sufficient and not an environmental limit risks, otherwise the possible outputs are less restrictive. IAC nice answer. —
