However, when working with approximate values it may be useful
to know whether the true value is positive or negative even
when for other values a little more or less is insignifcant.
One such case is temperature where the difference between -0.1
°C can be significantly different from +0.1 °C for practical
purpoises even when the difference between, say, 5 °C and 6 °C
isn't.

Practical porpoises will avoid -0.1°C because it makes swimming too difficult.
