Javascript无限对象 [英] Javascript Infinity Object

问题描述

我正在计算函数请求/秒的平均值，显然结果数有时太长所以它显示为Infinity，有没有办法将它舍入以便它只显示一个数字？或者在Infinity上做一个sleep（）/ wait（）？

I'm caclulating the mean value of a function's request/sec, appearently the result number sometimes is too long so it displays as Infinity, is there a way to round it so it show a number only? Or make a sleep()/wait() while it's on Infinity?

确切地说，我正在监视图表上的req / sec，当它是无穷大的时候行向上不是零

well to be exactly, im monitoring req/sec on a graph, when it's infinity the line goes up not towards zero

推荐答案

您很可能无意中除以零。

You are most likely unintentionally dividing by zero.

var num = 1/0;
console.log(num);
//>Infinity

有条件地检查除数是否为空。

Conditionally check that the divisor is not null.

您可以按如下方式检查整数的最大值：

You can check the maximum value of an integer as follows:

console.log([Number.MAX_VALUE, Number.MIN_VALUE]);
//>[1.7976931348623157e+308, 5e-324]

参见有关数字的官方 ECMA说明
