Question: When a variable has a value of 0.0 it losses its units.

when a variable has a value of 0.0 it seems to lose its units.


temp := 0.*Unit('degC');
                           temp := 0.
convert(temp, temperature, kelvin);
Error, (in convert/temperature) insufficient information for a temperature conversion
temp := 0.1e-1*Unit('degC');
                   temp := 0.01 Unit(°C)
Is this true?  How are you supposed to do calculations for example at 0.0 C?
convert(temp, temperature, kelvin);
                      273.1600000 Unit(K)
