15.11. __nv_fp4x4_e2m1

struct __nv_fp4x4_e2m1

__nv_fp4x4_e2m1 datatype

This structure implements the datatype for handling four fp4 floating-point numbers of e2m1 kind each.

The structure implements converting constructors and operators.

Public Functions

__host__ __device__ inline __nv_fp4x4_e2m1()

Constructor by default.

__host__ __device__ inline explicit __nv_fp4x4_e2m1(const __half2 flo, const __half2 fhi)

Constructor from a pair of __half2 data type values, relies on __NV_SATFINITE behavior for out-of-range values.

__host__ __device__ inline explicit __nv_fp4x4_e2m1(const __nv_bfloat162 flo, const __nv_bfloat162 fhi)

Constructor from a pair of __nv_bfloat162 data type values, relies on __NV_SATFINITE behavior for out-of-range values.

__host__ __device__ inline explicit __nv_fp4x4_e2m1(const double4 f)

Constructor from double4 vector data type, relies on __NV_SATFINITE behavior for out-of-range values.

__host__ __device__ inline explicit __nv_fp4x4_e2m1(const float4 f)

Constructor from float4 vector data type, relies on __NV_SATFINITE behavior for out-of-range values.
