When you press the CE button…

Implementing a function called ce().
When I press ce, I want to take the Anum variable again and calculate it, but the Bnum value keeps changing…

How can I change the value of Anum?

<script>

var num = 0 ;
var kiho ;
var flag = false;
var Anum = 0;
var Cnum = 0;

function backDo() {
total.value = total.value.substring(0, total.value.length-1);

if(total.value.length == 0){
clean();
}
}

function add (a) {
if(flag == false) {
total.value = “”;
flag = true;
}
total.value += a;
}

function cal(b) {
Anum = document.getElementById(“total”).value;
kiho = b ;
return total.value = “”;
}

function ce() {
//total.value = “”;
document.getElementById(“total”).value = “”;
Cenumber();
}

function Cenumber() {
Cnum = document.getElementById(“total”).value;

}

function merge () {

//Anum = document.getElementById(“total”).value;
//Cnum = Anum;
Cnum = Anum;
var Bnum = document.getElementById(“total”).value;

var result ;

switch (kiho) {

case ‘+’ : result = Number(Anum) + Number(Bnum) ;
//document.getElementById(“total”).value = result;
total.value = result;
break;

case ‘-‘ : result = Number(Anum) – Number(Bnum) ;
//document.getElementById(“total”).value = result;
total.value = result;
break;

case ‘*’ : result = Number(Anum) * Number(Bnum) ;
//document.getElementById(“total”).value = result;
total.value = result;
break;

case ‘/’ : result = Number(Anum) / Number(Bnum) ;
//document.getElementById(“total”).value = result;
total.value = result;
break;
}
}

function clean() {
if(flag == true) {
flag = false;
document.getElementById(“total”).value = “0”;
}
}

function plminus(){
total.value = -1* total.value;
return total.value;
}

function tan() {
if(total.value.length < 19) {
total.value = Math.tan((total.value * 3.141592) / 180);
}
return total.value;
}

function sin() {
if(total.value.length < 19) {
total.value = Math.sin((total.value * 3.141592) / 180);
}
return total.value;
}

function cos() {

if(total.value.length < 19) {
total.value = Math.cos((total.value * 3.141592) / 180);
}
return total.value;
}

function abs() {
if(total.value.length < 19) {
total.value = Math.abs(total.value);
}
return total.value;
}

function tenpow(){
if(total.value.length < 19) {
total.value = Math.pow(10,total.value);
}
return total.value;
}

function twopow(){
if(total.value.length < 19) {
total.value = Math.pow(2,total.value);
}
return total.value;
}

function pactorial() {
let result = 1;
for(let i=total.value; i>=1; i–) {
result = result * i;
total.value = result;
}
return result;
}

function boon() {
if(total.value.length < 19) {
total.value = 1/total.value;
}
return total.value;
}

function root() {
if(total.value.length < 19) {
total.value = Math.sqrt(total.value);
}

return total.value;
}

function jegob() {
total.value = Math.pow(total.value,2);
return total.value;
}
