# Is zero positive or negative?

Follow up to this question. Is $0$ a positive number?

In typical French mathematical usage, zero is both positive and negative. Or rather, in mathematical French “$x$ est positif” (literally “$x$ is positive”) allows the case $x = 0$, while “$x$ est positif strictement” (literally “$x$ is strictly positive”) does not.
Sometimes for computational purposes, it may be necessary to consider signed zeros, that is, treating $+0$ and $-0$ as two different numbers. One may think of this a capturing the different divergent behaviour of $1/x$ as $x\to 0$ from the left and from the right.
