While working on #120393, I realize that my fluent selectors were not working. So here is an improvement (not a fix unfortunately).

Hm, this seems quite confusing. If someone is matching on different numbers, say 0, 1, 100, and 1000, then the latter one will be different, which is pretty inconsistent.

I think it's a necessary compromise given the usage of f64 in FluentNumber. In reality, you're probably using one of the CLDR numerical selectors, rather than the number directly.

I agree. I thought of using a more complicated system which would take into account f64 maximum representable base-10 number but I think it's overkill.

The reason I wanted to match on the numbers was to change the sentence in the 1 case, and it will be the case of many other peoples and I think that in many languages phrases with numbers generally only care about 0, 1, >1. So to be safe I choose 100 as a low but consistent and predictable number.

I think this is a good step even if it's a bit inconsistent.
