クロージャを使用した数学演算の計算...？

Question

私はそれはそれはまた、整数に変換した後はNaNとして表示され、結果ブロックに閉鎖機能

を使用して電卓の演算子である

変更されたファイル。これがうまくいくはずです

var pradeep=(function(){ 
    // No need of these variables result = 0; sum_is=sub_is=mul_is=divn_is=0; 
    function manupulation(x,y){ 
     var sum_is = getsumValues(x,y); //use var otherwise global scope is used 
     var sub_is = getsubValues(x,y); 
     var mul_is = getmulValues(x,y); 
     var divn_is = getdivnValues(x,y); 
     return [sum_is,sub_is,mul_is,divn_is]; 
    } 
    function getsumValues(x,y){ 
     var sum_is = x+y; 
     return sum_is; 
    } 
    function getsubValues(x,y){ 
     var sub_is = x-y; 
     return sub_is; 
    } 
    function getmulValues(x,y){ 
     var mul_is = x*y; 
     return mul_is; 
    } 
    function getdivnValues(x,y){ 
     var divn_is = x/y; 
     return divn_is; 
    } 
    return{ 
     manupulation_value : function(x,y){ 
      return manupulation(x,y); 
     } 
    } 
})(); 

2番目のファイルにエラーがあります。

     details.Firstvalue = document.querySelector("#fnumber").value;

     details.SecondValue = parseInt(details.SecondValue); 
     details.result = 0; 
     //details.selectedOperation = document.querySelector("operation") 
     details.showdetails = function(){ 
      console.log(pradeep); 
      document.querySelector("#numberF").innerText = details.Firstvalue; 
      document.querySelector("#numberS").innerText = details.SecondValue; 
      function operationsMathematical(){
