Usage: for quantization and dequantization of inputs/outputs is different for different qmodes for qmode - 0, 1, 2 and 3: quantized_value = round(float_value * qn) dequantized_value = quantized_value / qn for qmode - 9: quantized_value = round(float_value / qn) + offset dequantized_value = (float_value - offset )* qn
