It's PLUS Zero degrees

The artist formerly known as wrote:

Personally, if I were to design my own thermometer, I would choose the
simplest method. I would create a rule that would determine whether to
display a "+" or "-", and I would display it. Consider the rule that
display "+" for values = 0. Now consider a rule that displays "+" for
values 0. The former results in +0 while the latter results in -0 being
displayed.

You must realize that behind every electronic device there was a human being
who designed it. It is completely arbitrary to use +0, -0, or just 0, as
they all mean the same thing. Likewise, it is futile to attempt to analyze
this with any sort of expectations of insight into WHY a particular
convention was used.
