  No, I don't say nothing ugly about your algorithm. Even by absurd it is
wrong I don't dare to do this... ( until I not understad it 100% )
 I'm working with DS1620 but it seems the hi res algorithm is the same. If
count_per_degree is almost constant ( fluctuating between 0x_40 to 0x_65 )
count_remain have a fluctuation from less than count_per_degree to 0x_01df
at the constant test temperature of about 20 C.
I think is too much, because the division between these two should be
almost constant and is not ...
Thanks, Vasile
