Intl.Locale.prototype.numberingSystems

The Intl.Locale.prototype.numberingSystems property is an accessor property that returns one or more unique numbering system identifiers according to the numeral system used by the Locale.

Description

A numeral system is a system for expressing numbers. The numberingSystem property helps to represent the different numeral systems used by various countries, regions, and cultures around the world. As with most internationalization schemas, the numeral systems that can be represented in a Locale object by numberingSystem are standardized by Unicode. A table of the standard Unicode numeral systems can be seen below.

Examples

Obtaining supported numberingSystem values via the locale string

In the Unicode locale string spec, the values that numberingSystem represents correspond to the key nu. nu is considered a locale string "extension subtag". These subtags add additional data about the locale, and are added to locale identifiers by first adding the -u key. To set the numberingSystem value via the string argument to the Locale constructor, first add the -u extension key. Next, add the -nu extension key to indicate that you are adding a value for numberingSystem. Finally, add the numberingSystem value to the string.

List supported number system for a given Locale.

let arEG = new Intl.Locale("ar-EG");
console.log(arEG.numberingSystems); // logs ["arab"]
let ja = new Intl.Locale("ja");
console.log(ja.numberingSystems); // logs ["latn"]
