Intl Numberformat Either 0 Or Two Fraction Digits

When it comes to formatting numbers in your code, the Intl.NumberFormat object is a handy tool that allows you to display numbers in a locale-specific way. One common requirement when working with numbers is to display decimal fractions in a particular format, such as displaying exactly zero or two decimal digits.

To achieve this specific formatting using Intl.NumberFormat, you can set the minimumFractionDigits and maximumFractionDigits options accordingly. When you want to display either 0 or two fractional digits, you can set these options to the values that fit your needs.

Here's how you can use Intl.NumberFormat to achieve this formatting in your code:

// Create a new Intl.NumberFormat object with the desired options
const numberFormatter = new Intl.NumberFormat('en-US', {
  minimumFractionDigits: 0,
  maximumFractionDigits: 2
});

// Format the number using the created formatter
const formattedNumber = numberFormatter.format(1234.56789);

console.log(formattedNumber); // Output: "1,234.57"

In the example above, we first create a new Intl.NumberFormat object, specifying the 'en-US' locale for English formatting conventions. Then, we set the minimumFractionDigits option to 0 and the maximumFractionDigits option to 2. This configuration ensures that the formatted number will display either 0 or two decimal digits.

After creating the formatter, we use the `format()` method to format a sample number, 1234.56789, according to the specified options. The resulting formatted number will be "1,234.57" in this case.

By adjusting the minimumFractionDigits and maximumFractionDigits options in the Intl.NumberFormat constructor, you can easily control the number of decimal digits displayed in the formatted output based on your requirements.

It's important to note that the Intl.NumberFormat object provides powerful features for formatting numbers in a locale-specific manner, making it easier to display numbers according to various formatting rules and conventions across different regions.

So, the next time you need to format numbers in your code and display either 0 or two decimal digits, remember to leverage Intl.NumberFormat with the appropriate options to achieve the desired outcome effortlessly. Happy coding!
