js除法运算保留2位小数

let num1 = 10;
let num2 = 3;
let result = (num1 / num2).toFixed(2);
console.log(result); // 输出 "3.33"

let num1 = 10;
let num2 = 3;
let result = parseFloat((num1 / num2).toFixed(2));
console.log(result); // 输出 3.33

let num1 = 10;
let num2 = 3;
let result = Math.round((num1 / num2) * 100) / 100;
console.log(result); // 输出 3.33

let num1 = 10;
let num2 = 3;
let formatter = new Intl.NumberFormat('en-US', {
    minimumFractionDigits: 2,
    maximumFractionDigits: 2,
});
let result = formatter.format(num1 / num2);
console.log(result); // 输出 "3.33"

// 首先需要引入 Decimal.js 库
const Decimal = require('decimal.js');

let num1 = new Decimal(10);
let num2 = new Decimal(3);
let result = num1.div(num2).toFixed(2);
console.log(result); // 输出 "3.33"
