> I can not tell if it is 30 or 31 °C outside. Most thermostats I've seen allow changes of 0.5 degrees C. So it seems that the thermostat manufacturers feel that the majority of users can tell a difference. And sometimes 1 degree C delta is too much for me in a room (e.g. 21.0 is comfortable, 22.0 is not, 21.5 is just right). So it's obviously a personal preference, but at least for me, I can tell a difference between 0.5 degrees C. And thus for my use case, whole integers in F is a slightly superior user experience since it avoid fractions.
