Enum Values

dnnl_data_type_undef

Undefined data type, used for empty memory descriptors.

dnnl_f16

16-bit/half-precision floating point.

dnnl_bf16

non-standard 16-bit (bfloat16 w/ 7 bit mantissa) floating point.

dnnl_f32

32-bit/single-precision floating point.

dnnl_s32

32-bit signed integer.

dnnl_s8

8-bit signed integer.

dnnl_u8

8-bit unsigned integer.

dnnl_f64

64-bit/double-precision floating point.

dnnl_data_type_max

Parameter to allow internal only data_types without undefined behavior.

This parameter is chosen to be valid for so long as sizeof(int) >= 2.
