.toFixed not for .0 *

问题描述

我有几个值:

var one = 1.0000
var two = 1.1000
var three = 1.1200
var four = 1.1230

和功能:

function tofixed(val)
{
   return val.toFixed(2);
}

此返回:

1.00
1.10
1.12
1.12 

实时

我希望在点号-2之后有最大尺寸，但前提是！= 0之后的数字.所以我想收到:

I want maximum size after dot - 2, but only if numbers after for != 0.So i would like receive:

1
1.1
1.12
1.12 

我该怎么做?

推荐答案

.toFixed(x)返回字符串.只需再次将其解析为浮点数即可:

.toFixed(x) returns a string. Just parse it as a float again:

return parseFloat(val.toFixed(2));
