whoops - I totally misread your question, I was thinking you wanted the TYPE
which
would hold a max value corresponding to 15 bits.
It turns out that I've been working in this area recently. I would suggest
skipping
the mpl layer and using BOOST_STATIC_CONSTANT directly. The reason
is that mpl includes some operations like next which might not work for 2^64
etc.
template <int K>
struct unsigned_integral_max_value struct {
BOOST_STATIC_CONSTANT( boost::uintmax_t, value = ((boost::uintmax_t)1 <<
K)-1);
};
Isn't this pretty much exactly what Christian was using before? If so, I'd guess it still has the same compile-time-overflow issues. But maybe I'm misremembering the original problem :/
