    for(var i=0;i<arr.length;i++){
        num = math.add(math.bignumber(arr[i]), math.bignumber(num)).toString(); // 加
    }
    console.log(num) // 加
    console.log(math.subtract(math.bignumber(900000000000), math.bignumber(9.2)).toString())  // 减
    console.log(math.multiply(math.bignumber(9), math.bignumber(9.12)).toString()) // 乘
    console.log(math.divide(math.bignumber(9), math.bignumber(3)).toString()) // 除

使用math.js插件
