Follow-up Comment #9, bug #53167 (project octave):

It's doing the right thing. But we might want to use digits10 + 1 for floating
point types. The value of digits10 isn't the maximum number of digits that can
be represented at all, it's the maximum number of digits that can always be
represented without any loss of precision.

flintmax("double") is close to 1e16, but not quite. and flintmax("single") is
closer to 1e7. So 15 and 6 are correct.
