Return value

A new object with properties reflecting the locale and number formatting options computed during the initialization of the given NumberFormat object.

Description

The resulting object has the following properties:

locale
The BCP 47 language tag for the locale actually used. If any Unicode extension values were requested in the input BCP 47 language tag that led to this locale, the key-value pairs that were requested and are supported for this locale are included in locale.
numberingSystem
The value requested using the Unicode extension key "nu" or filled in as a default.
style
useGrouping
The values provided for these properties in the options argument or filled in as defaults.

Only one of the following two groups of properties is included:

minimumIntegerDigits
minimumFractionDigits
maximumFractionDigits
The values provided for these properties in the options argument or filled in as defaults. These properties are present only if neither minimumSignificantDigits nor maximumSignificantDigits was provided in the options argument.
minimumSignificantDigits
maximumSignificantDigits
The values provided for these properties in the options argument or filled in as defaults. These properties are present only if at least one of them was provided in the options argument.

var de = new Intl.NumberFormat('de-DE');
var usedOptions = de.resolvedOptions();

usedOptions.locale;                // "de-DE"
