1、分转元

// 精度 分转元export const regFenToYuan = (fen) =>{    var num = fen;    num=fen*0.01;    num+='';    var reg = num.indexOf('.') >-1 ? /(\d{1,3})(?=(?:\d{3})+\.)/g : /(\d{1,3})(?=(?:\d{3})+$)/g;    num=toDecimal2(num.replace(reg,'$1'));    return num};

2、元转分

// 精度 元转分export const regYuanToFen = (arg1, multiple:any) =>{    var m=0,        s1=arg1.toString(),        s2=multiple.toString();    try{m+=s1.split(".")[1].length}catch(e){}    try{m+=s2.split(".")[1].length}catch(e){}    return Number(s1.replace(".",""))*Number(s2.replace(".",""))/Math.pow(10,m)}
