This is a jQuery plugin which allows developers to easily format numbers for display use. Allows users to replace numbers inline in a document, or return a formatted number for other uses.

See our jQuery Number Format article for more information.

The number method takes up to four parameters, but only the first one is required.

1. Number: The number you want to format.

    $.number( 5020.2364 ); // Outputs 5,020
   

2. Decimal Places: The number of decimal places you wish to see. Defaults to 0.

    $.number( 5020.2364, 2 ); // Outputs: 5,020.24
   

3. Decimal Separator: The character(s) to use as a decimal separator. Defaults to '.'.

    $.number( 135.8729, 3, ',' ); // Outputs: 135,873
   

4. Thousands Separtor: The character(s) to use as a thousands separator. Defaults to ','.

    $.number( 5020.2364, 1, ',', ' ' ); // Outputs: 5 020,2	
   

$('.selector').number( 1234, 2 ); // Changes the text value of the element matching selector to the formatted number.

Assuming we have the following structure:

<p>
  <span class="number">1025.8702</span>
  <span class="number">18023</span>
  <span class="number">982.3</span>
  <span class="number">.346323</span>
</p>

We can use this JavaScript:

// the 'true' signals we should read and replace the text contents of the target element.
$('span.number').number( true, 2 )

And come away with this result:

<p>
  <span class="number">1,025.87</span>
  <span class="number">18,023.00</span>
  <span class="number">982.30</span>
  <span class="number">0.35</span>
</p>
