UnverifiedFP32 uses 32 binary bits to represent a number (1 sign bit, 8 exponent bits, 23 mantissa bits) and can accurately represent approximately 7 significant decimal digits.69% similarUnverifiedCompared to FP16 original precision, FP8 quantization typically causes no more than 1–2% performance degradation on mainstream benchmarks.68% similarUnverifiedBF16 uses 1 sign bit, 8 exponent bits, and 7 mantissa bits, sacrificing precision while retaining the same dynamic range as FP32.66% similarUnverifiedfloat32的有效精度约为7位十进制数字，float64约为15位61% similarUnverifiedThe maximum value of FP16 is approximately 65504; its dynamic range is smaller than that of BF16 and is prone to overflow issues.61% similar
