Description:

This is a special numeric value representing any value greater than Number.MAX_VALUE. This value is represented as "Infinity". This value resembles an infinity in its mathematical behavior. For example, anything multiplied by POSITIVE_INFINITY is POSITIVE_INFINITY, and anything divided by POSITIVE_INFINITY is zero.

Because POSITIVE_INFINITY is a constant, it is a read-only property of Number.

You can access this property using the following syntax:

var val = Number.POSITIVE_INFINITY;

Example:

Here is an example showing usage of this property:

<html>
<head>
<script type="text/javascript">
<!--
function showValue()
{
   var bigNumber = Number.MAX_VALUE * 2
   if (bigNumber == Number.POSITIVE_INFINITY) {
      alert("Value of bigNumber : " + bigNumber );
   }
}
//-->
</script>
</head>
<body>
<p>Click the following to see the result:</p>
<form>
<input type="button" value="Click Me" onclick="showValue();" />
</form>
</body>
</html>

This will produce following result:
