Does zero have a sign?

In ordinary arithmetic, the number 0 does not have a sign, so that −0, +0 and 0 are identical. Negatively signed zero echoes the mathematical analysis concept of approaching 0 from below as a one-sided limit, which may be denoted by x → 0−, x → 0−, or x → ↑0.

Is Negative 0 a temperature?

It is common to use the sign −0 to denote that the temperature is near, but below zero degrees. If the temperature is −0.1, but your display does not show decimal numbers, then the machine would probably display −0∘.

What does negative temperature feel like?

Below minus-20, however, this calculus changes. Beyond this threshold, the thermal grace period shrinks rapidly and disappears altogether. By about 30 below the cold doesn’t feel like cold anymore — it’s just pure, unadulterated pain; a sharp, burning sensation
