JavaScript format number as currency string | Example code

  • by

Use Intl.NumberFormat number formatter (part of the Internationalization API) to format numbers as currency strings in JavaScript. This method formats numbers using custom locale parameters.

The Intl.NumberFormat() constructor accepts two arguments, the first being a locale string, with which we define the locale we want to format to:

   const price = 1500000.15;

   let US = Intl.NumberFormat('en-US');
   let IN = Intl.NumberFormat('en-IN');

   console.log("US Locale: " + US.format(price));
   console.log("Indian Locale: " + IN.format(price));

Output: US Locale: 1,500,000.15

Indian Locale: 15,00,000.15

The second argument can be used to specify the options you want to apply while formatting.

  • style
  • currency
  • useGrouping
  • maximumSignificantDigits
