I am not talking floating point. digital camera sensors have same output voltages feeding 12 bit output A/Ds as they feeding 8 bit output A/Ds. There is SCALING involved and the the advantage in using 12 bit vs. 8 bit is NOT a higher recorded signal level, it is finer gray scale and smaller step size.
