WebAug 31, 2024 · A Half is a binary floating-point number that occupies 16 bits. With half the number of bits as float, a Half number can represent values in the range ±65504. More formally, the Half type is defined as a base-2 16-bit interchange format meant to support the exchange of floating-point data between implementations. WebDec 3, 2024 · Bfloat16 has three fewer bits in the significand than fp16, but three more in the exponent. And it has the same exponent size as fp32. Consequently, converting from fp32 to bfloat16 is easy: the exponent is kept the same and the significand is rounded or truncated from 24 bits to 8; hence overflow and underflow are not possible in the conversion. gachot stool
