I thought the minimum increment of the ds1621 is 0.5°... How should one be able to get more precision if the sensor doesn't support it? Maybe you could get an average over several values but that wouldn't be more precise... There is no point in trying to get a better resolution if the sensor can't supply better values. You could probably calculate a moving average over several values and "cheat" another decimal place this way
