	GPUdDefault () Float16Impl()=default

	GPUd () bool IsNegative() const noexcept
	Checks if the value is negative.

	GPUd () bool IsNaN() const noexcept
	Tests if the value is NaN.

	GPUd () bool IsFinite() const noexcept
	Tests if the value is finite.

	GPUd () bool IsPositiveInfinity() const noexcept
	Tests if the value represents positive infinity.

	GPUd () bool IsNegativeInfinity() const noexcept
	Tests if the value represents negative infinity.

	GPUd () bool IsInfinity() const noexcept
	Tests if the value is either positive or negative infinity.

	GPUd () bool IsNaNOrZero() const noexcept
	Tests if the value is NaN or zero. Useful for comparisons.

	GPUd () bool IsNormal() const noexcept
	Tests if the value is normal (not zero, subnormal, infinite, or NaN).

	GPUd () bool IsSubnormal() const noexcept
	Tests if the value is subnormal (denormal).

	GPUd () Derived Abs() const noexcept
	Creates an instance that represents absolute value.

	GPUd () Derived Negate() const noexcept
	Creates a new instance with the sign flipped.

	GPUd () static bool AreZero(const Float16Impl &lhs
	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.
