Well, as a physicist for me 1 J and 1 Nm are the same. I would reject and never use a library that forces me to distinguish physically identical quantities just because I use a different name for the unit.
fully agree, distinguishing between torque and energy is artificial. And just look how much complications it adds to the library! Whole new concept of anonymous_quantity, serialization (outputting units values) burden, etc... Displaying a unit using correct unit should be left up for the user - he chooses what name he wants displayed. The library could only take care to correctly convert the value for output requested so that it matches required unit - eg. passed as a string: "kNm","Nm","J","kWh" or "kg m^2 s^-2" -- Janek Kozicki |
