Sorry, this did not come out quite right! Thanks J-P. ... Zero is even harder. :-)
You've probably seen the T-shirt: "There are 10 kinds of people: those who understand binary and those who don't" or similar... ------------ back to the problem --------------------------------- Anyway, the problem here is actually with the associated units, which are internally stored as Kelvins and only converted to degC for display. Set it to Kelvin and small enough integers will be accurate. In your case, 1 degC is actually represented as a fractional number (274.15) internally and does not have an exact binary representation.
