#Informative

This proposal is based on the LDML spec, C.11 Language Plural Rules:

• http://unicode.org/reports/tr35/tr35-numbers.html#Language_Plural_Rules

#Prior Art

• Java: Class PluralRules

#Usage

let o = new Intl.PluralRules("en", {
    type: "cardinal" // default type
});
console.log(o.select(0)); // "other"
console.log(o.select(1)); // "one"
console.log(o.select(2)); // "other"

Support for ordinals is also included:

let o = new Intl.PluralRules("en", {
    type: "ordinal"
});
console.log(o.select(21)); // "one"
console.log(o.select(22)); // "two"
console.log(o.select(23)); // "few"
console.log(o.select(24)); // "other"

#TODO

• new Intl.PluralRules("en").format(1.02); should produce "other"
• Bikeshed on Intl.PluralRules
• Spec pluralCategories resolution
