It should say "Floating point values which are NOT a number (Nan)
cannot be serialized to text based archives.".

No it just means that you can't store the float that results from
an undefined operation such as x/y where y == 0.0 .  I would
recommend that you using something like

serialize(Archive &ar, version ..)
    assert(! is_nan(f));
    ar << f;
}

or something like that.
