The Infinity property is a numeric value that represents positive or negative infinity.
Infinity属性表示正无穷大或负无穷大。
Infinity is displayed when a number is higher than 1.7976931348623157E+10308, and -Infinity is displayed when a number is lower than -1.7976931348623157E+10308.
当一个数字大于1.7976931348623157E+10308时正无穷,当一个数字小于-1.7976931348623157E+10308时负无穷。
Infinity |
Note: Anything divided by Infinity is 0 and anything multiplied by Infinity is Infinity.
注意:任意独立的元素与Infinity对比为0,任意多个元素与Infinity对比为无穷。
In this example we will show what happens if a number exceeds the infinity limit:
在下面的例子中,我们将演示一个数字于无穷比较的结果:
<script type="text/javascript"> var t1=1.7976931348623157E+10308 document.write("<br />") var t2=-1.7976931348623157E+10308 </script> |
The output of the code above will be:
输出结果为:
Infinity |
