Intl.Locale.prototype.numberingSystem
The Intl.Locale.prototype.numberingSystem
property is an accessor property that returns 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
Setting the numberingSystem
value 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.
let locale = new Intl.Locale("fr-Latn-FR-u-nu-mong");
console.log(locale.numberingSystem); // Prints "mong"
Setting the numberingSystem
value via the configuration object argument
The Intl.Locale
constructor has an optional configuration object argument, which can be used to pass extension types. Set the numberingSystem
property of the configuration object to your desired numberingSystem
value and pass it into the constructor.
let locale = new Intl.Locale("en-Latn-US", { numberingSystem: "latn" });
console.log(locale.numberingSystem); // Prints "latn"
