Functions

__host__ ​ __device__ ​ __nv_fp8x4_e4m3::__nv_fp8x4_e4m3 ( const double4 f ) [inline]
Description

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

__host__ ​ __device__ ​ __nv_fp8x4_e4m3::__nv_fp8x4_e4m3 ( const float4 f ) [inline]
Description

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

__host__ ​ __device__ ​ __nv_fp8x4_e4m3::__nv_fp8x4_e4m3 ( const __nv_bfloat162 flo, const __nv_bfloat162 fhi ) [inline]
Description

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

__host__ ​ __device__ ​ __nv_fp8x4_e4m3::__nv_fp8x4_e4m3 ( const __half2 flo, const __half2 fhi ) [inline]
Description

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

__nv_fp8x4_e4m3::__nv_fp8x4_e4m3 ( )
Description

Constructor by default.

__host__ ​ __device__ ​ __nv_fp8x4_e4m3::operator float4 ( ) const [inline]
Description

Conversion operator to float4 vector data type.
