学习使用js保留两位小数同时去掉小数末尾多余的00

前言

let number  =50000000;let new_number = number / 10000;console.log('formatter-new_number===', new_number);return new_number.toFixed(2) + '万';

会发现整数使用toFixed(2)，之后会有多余的.00

去除00方法

let number  =50000000;
let new_number = number / 10000;
console.log('formatter-new_number===', new_number);
new_number = unifyNumber(new_number) + '万';//独立的保留两位小数的方法
function unifyNumber(num) {if (num === '') {return 0} else {let handleNum = parseFloat(num)let isToFixed = handleNum.toString().includes('.') && handleNum.toString().split('.')[1].length > 2if (isToFixed) {return handleNum.toFixed(2)} else {return handleNum}}
}

效果图如下：
