I'm not sure I understand this use-case. We already have the INF and NAN
constants for obtaining those values, and the standard IEEE 754 operations
which produce these values are implemented (1/0 for INF, 0/0 for NAN,
etc.)
Ah, so then it is fine, thanks for the education. Then it'd stay by DBL_DIG
and DBL_EPSILON. While DBL_MAX/ DBL_MIN could still be useful in some case
(fe one would want to explicitly know the values), in most case it'd be
covered by INF.
It can't hurt to add them anyway, though.
