Ejemplos
Usando format
Use the format
getter function for formatting a single currency value, here for Russia:
js
var options = { style: "currency", currency: "RUB" };
var numberFormat = new Intl.NumberFormat("ru-RU", options);
console.log(numberFormat.format(654321.987));
// → "654 321,99 руб."
Usando format
con map
Use the format
getter function for formatting all numbers in an array. Note that the function is bound to the NumberFormat
(en-US) from which it was obtained, so it can be passed directly to Array.prototype.map
.
js
var a = [123456.789, 987654.321, 456789.123];
var numberFormat = new Intl.NumberFormat("es-ES");
var formatted = a.map(numberFormat.format);
console.log(formatted.join("; "));
// → "123.456,789; 987.654,321; 456.789,123"
