12.2. __half2

struct __half2

This structure implements the datatype for storing two half-precision floating-point numbers. The structure implements assignment, arithmetic and comparison operators, and type conversions.

NOTE: __half2 is visible to non-nvcc host compilers

Emtpy default constructor, result is uninitialized.

__host__ __device__ inline constexpr __half2(const __half &a, const __half &b): Constructor from two __half variables.

__host__ __device__ inline __half2(const __half2 &&src): Move constructor, available for C++11 and later dialects.

__host__ __device__ inline __half2(const __half2 &src): Copy constructor.

__host__ __device__ inline __half2(const __half2_raw &h2r): Constructor from __half2_raw.

__host__ __device__ operator __half2_raw() const: Conversion operator to __half2_raw.

__host__ __device__ __half2 &operator=(const __half2 &&src): Move assignment operator, available for C++11 and later dialects.

__host__ __device__ __half2 &operator=(const __half2 &src): Copy assignment operator.

__host__ __device__ __half2 &operator=(const __half2_raw &h2r): Assignment operator from __half2_raw.
