This is a special numeric value representing any value greater than Number.MAX_VALUE. This value is represented as "Infinity". It 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.
由于正无穷大是一个常数,因此它是number的只读属性。
使用以下语法来使用active_infinity。
var val=Number.POSITIVE_INFINITY;
尝试以下示例以了解如何使用posal_infinity。
<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>
