I did. But who on earth tagged it as controversial?

(someone who has found a way to enter the imaginary domain, I suppose)

No, I did, because the natural numbers are often defined to NOT include 0 :P.

Doesn't one usually speak of "greater" rather than "superior" in mathematics? I don't think I've ever seen it phrased like this.

you're probably right, thx.

That's why I added the second translation, actually.

I was going to say that this was probably something from the French, but "superior to" is still very valid, IMO, even in English. More erudite books might use it. But yes, the more common natural thing would be "greater than".

I'd like to go back to this "iff"

Is it really possible to use this "word" in a sentence like this one?

I believe it's just a short form of "if and only if" in logical formulas, for example you certainly might write: "For any p, q, and r: (p & q) & r iff p & (q & r)", but it's not a real sentence.

Could you really "iff" in a normal sentence, like in the definition of a natural integer? Maybe you still have to write "An integer is natural if and only if it is greater or equal to 0"?

I think it is used in what you call "normal" sentences.
For example in the Wikipedia article, there are examples for it:
