static bool	AreZero (const BFloat16Impl &lhs, const BFloat16Impl &rhs) noexcept
	IEEE defines that positive and negative zero are equal, this gives us a quick equality check for two values by or'ing the private bits together and stripping the sign. They are both zero, and therefore equivalent, if the resulting value is still zero. More...
