朋友是做财务的，由于工作时间不长，每次将数字转为大写人民币的时候，总是提心吊胆的，生怕弄错了。而且，如果是整数的话，还好，但是有小数的时候就比较费劲了，比如123.45，转成大写应该是壹佰贰拾叁元肆角伍分。然后就找到我，问我有没有什么办法？
简单啊，做一个转换程序不就可以了嘛？而且网上现成的一大把。出于好玩，所以使用Vue做了一个人民币大写转换器，在https的支持下，可以使用复制，朗读功能。还贴心的做了一个大写人民币参照表。
先看一眼成品
下面说说代码，及其简单哦！
创建一个Vue工程，在main.js中引入ant design
import App from './App.vue'
import Antd from 'ant-design-vue'
import 'ant-design-vue/dist/antd.less'
Vue.use(Antd)
直接再App.vue上完成吧。
