boost::multiprecision::mp_float will behave like a POD.

That would mean you could copy it with memcpy. But that's not what you intend to say, is it?
No, just normal stuff such as instances of boost::multiprecision::mp_float constructed and copied from other PODs like a regular float, double or long double.
This has little to do with POD-ness, FWIW. You should find some other way to describe it (e.g. "they behave like the built-in numeric types").
For example:
boost::multiprecision::mp_float x = 4.4; boost::multiprecision::mp_float y = x / 3;
std::cout << std::setprecision(std::numeric_limits<boost::multiprecision::mp_float>::digits10) << std::scientific << boost::multipreccision::sqrt(x / y) << std::endl;
... and so on...
But if you have a sequence of them, they can be copied with std::copy or set with std::fill, and the lot.
Sincerely, Chris.
