Plural behavior with count == 0

H3llK33p3r commented 1 month ago

Reporting a bug?

Using the example in the documentation with 'car' and 'apple' : https://vue-i18n.intlify.dev/guide/essentials/pluralization.html There is a strange behavior with car when the second argument is 0 (count). Plural is used instead of singular.

The default plural rule with the first ternary operation is bugged if we provide 0 !

function pluralDefault(choice, choicesLength) {
    choice = Math.abs(choice);
    if (choicesLength === 2) {
        // prettier-ignore
        return choice
            ? choice > 1
                ? 1
                : 0
            : 1;
    }
    return choice ? Math.min(choice, 2) : 0;
}

Expected behavior

For count from 0 to 1, singular must be used ?

This looks like it is working as intended to me, only 1 can be singular, anything more or less is not singular.

Your example actually demonstrates this well

zero cars (or) no cars
zero apples (or) no apples

Using singular for zero amounts would be grammatically incorrect, this probably differs across languages.

Ok I understand, both can be used depending on the context. It's strange, as a French, to see plural with a 0 quantity ! Thank you for your response.
