Formatting a number as currency using CSS

Just wondering if anyone knows whether it is possible to format the content of an element as currency using only CSS. It would be nice to have how the value is presented in CSS if possible, can't find anything though so I'm not holding my breath :)

<!DOCTYPE html>
<html>
<head>
    <style type="text/css">
        .dollars:before { content:'$'; }
    </style>
</head>
<body>
    Pure CSS: <span class="dollars">25153.3</span>
    <br />
    Ideal format: <span>$25,153.30</span>
</body>
</html>

That example comes out as:

Pure CSS: $25153.3

Ideal format: $25,153.30

Also I'm aware that it's fairly trivial using javascript - http://css-tricks.com/snippets/javascript/format-currency/.

The currency format can be achieved with CSS and a bit of Javascript which is needed for the parsing of the number to add the commas. A CSS class adds the additional styling like negative (red) or currency sign (i.e. $ Dollar sign). The approach is a follows:

1) Convert the value to number (adds the commas based on the locale)

Number(value).toLocaleString('en');

2) Add a class to determine if it is negative or positive value (i.e. red color)

.enMoney::before {
    content:"$";
}
.negMoney {
    color:red;
}
