Functions
constexpr fp16	native::operator""_fp16 (long double v) noexcept
	Round a literal through binary32 to fp16.
constexpr bool	std::isnan (::native::fp16 x) noexcept
	Classify the stored bits as NaN without performing a floating-point conversion.

	Round a literal through binary32 to bf16.
constexpr bf16	native::fast_to_bf16 (float f) noexcept
constexpr bf16	native::fast_to_bf16 (bf16 f) noexcept
	Return an already converted bfloat16 unchanged.
constexpr bool	std::isnan (::native::bf16 x) noexcept
	Classify the stored bits as NaN without performing a floating-point conversion.
template<typename T>
