Change numbers into a comma-separated style containing two decimal points using javascript

I have been working on a JavaScript function to convert numbers into a comma-separated format with two decimal places:

Here is my current code snippet:

Number(parseFloat(n).toFixed(2)).toLocaleString('en');

The issue with this code is that it does not show two decimal places (.00) for whole numbers.

I am looking for the following results for a set of numbers:

10000 => 100,00.00
123233.12 => 123,233.12
300000.5  => 300,000.50

Any help or suggestions would be greatly appreciated. Thank you.

Answer №1

If you want to display decimal values up to 2 digits, you can simply utilize the minimumFractionDigits option within the toLocaleString function.

// This will output 3,000.00
3000..toLocaleString('en', {
    minimumFractionDigits: 2
});

// And this will result in 123,233.12
123233.12.toLocaleString('en', {
    minimumFractionDigits: 2
});

If you do not require additional logic beyond formatting for display purposes, you may omit the parseFloat, toFixed, and Number functions altogether.
