toLocaleString，百分比和Firefox 38 [英] toLocaleString, Percentages, and Firefox 38

问题描述

我正在尝试将百分比格式设置为三个有效数字.我想要一个很小的百分比，例如1075/107175175，显示为0.0001％.

I'm trying to format a percentage to have three significant figures. I'd like a fairly small percentage, something like 1075 / 107175175, to show up as 0.0001%.

var x = 1075 / 107175175;
console.log(x.toLocaleString('en-us', {
    style: 'percent', minimumSignificantDigits: 1
}));

我得到的是"0.00100303078581397％".这是如何在Javascript中实现浮点数还是存在问题?

What I'm getting instead is '0.00100303078581397%.' Is this an issue with how floating point numbers are implemented in Javascript or a bug?

推荐答案

您是否尝试过使用maximumSignificantDigits:1?

Have you tried using maximumSignificantDigits: 1?

console.log(x.toLocaleString('en-us', {
