Intl.PluralRules.prototype.resolvedOptions()

None.

A new object with properties reflecting the options computed during the initialization of this PluralRules object. The object has the following properties, in the order they are listed:

locale

The BCP 47 language tag for the locale actually used, determined by the locale negotiation process. No Unicode extension key will be included in the output.

type

The value provided for this property in the options argument, with default filled in as needed. It is either "cardinal" or "ordinal". The default is "cardinal".

minimumIntegerDigits, minimumFractionDigits, maximumFractionDigits Optional

The value provided for these properties in the options argument, with defaults filled in as needed. These properties are present only if neither minimumSignificantDigits nor maximumSignificantDigits was provided in the options argument.

minimumSignificantDigits, maximumSignificantDigits Optional

The value provided for these properties in the options argument, with defaults filled in as needed. These properties are present only if at least one of them was provided in the options argument.

pluralCategories

An Array of plural categories used by the given locale, selected from the list "zero", "one", "two", "few", "many" and "other".

roundingIncrement

The value provided for this property in the options argument, with default filled in as needed. It is one of 1, 2, 5, 10, 20, 25, 50, 100, 200, 250, 500, 1000, 2000, 2500, and 5000. The default is 1.

roundingMode

The value provided for this property in the options argument, with default filled in as needed. It is one of "ceil", "floor", "expand", "trunc", "halfCeil", "halfFloor", "halfExpand", "halfTrunc", and "halfEven". The default is "halfExpand".

roundingPriority

The value provided for this property in the options argument, with default filled in as needed. It is either "auto", "morePrecision", or "lessPrecision". The default is "auto".

trailingZeroDisplay

The value provided for this property in the options argument, with default filled in as needed. It is either "auto" or "stripIfInteger". The default is "auto".

The code below shows the construction of a PluralRules object, followed by logging of each of the resolved options.

// Create a PluralRules instance
const de = new Intl.PluralRules("de-DE", {
  maximumSignificantDigits: 2,
  trailingZeroDisplay: "auto",
});

// Resolve the options
const usedOptions = de.resolvedOptions();
console.log(usedOptions.locale); // "de-DE"
console.log(usedOptions.pluralCategories); // Array ["one", "other"]
console.log(usedOptions.type); // "cardinal"
console.log(usedOptions.minimumIntegerDigits); // 1
console.log(usedOptions.minimumFractionDigits); // undefined (maximumSignificantDigits is set)
console.log(usedOptions.maximumFractionDigits); //undefined (maximumSignificantDigits is set)
console.log(usedOptions.minimumSignificantDigits); // 1
console.log(usedOptions.maximumSignificantDigits); //2
console.log(usedOptions.roundingIncrement); // 1
console.log(usedOptions.roundingMode); // "halfExpand"
console.log(usedOptions.roundingPriority); // "auto"
console.log(usedOptions.trailingZeroDisplay); // "auto"
