mj-calculation v1.0.4

前言

因为JavaScript这门语言在计算浮点数时存在精度丢失，所以封装了加减乘除四个方法，每个方法只允许传两个参数，参数之间需要用逗号隔开。

1、下载安装指令

npm install mj-calculation --save

2、暴露的方法

方法名	描述
addition	加法
subtraction	减法
multiplication	乘法
division	除法

3、使用方式

CDN

<script src="./node_modules/mj-calculation/index.js"></script>

<script>
    console.log('calculation:', calculation.addition(0.1, 0.2));
    // 0.3
    console.log('calculation:', calculation.subtraction(0.1, 0.2));
    // -0.1
    console.log('calculation:', calculation.multiplication(0.1, 0.2));
    // 0.02
    console.log('calculation:', calculation.division(0.1, 0.2));
    // 0.5
</script>

vue

import { addition, subtraction, multiplication, division } from "mj-calculation";
// const calculation = require("mj-calculation");

export default {
    name: "App",
    data() {
        return {};
    },
    mounted() {
        // console.log("calculation:", calculation);
        // calculation: {addition: ƒ, subtraction: ƒ, multiplication: ƒ, division: ƒ}

        console.log(addition, subtraction, multiplication, division);
        // 使用方式与CDN一样
    },
};
