Question

Lets say I have a string in JavaScript with binary data in it. It may look like this:

var binary = \'00001000010001000101010100001110\';

To convert bin to hex and reverse i use these functions:

function bintohex()
{    
     mybin = document.getElementById('bin').value;

     z = -1; number = 0;
     for(i = mybin.length; i > -1; i--) 
     {
         //Every 1 in binary string is converted to decimal and added to number
         if(mybin.charAt(i) == "1"){
             number += Math.pow(2, z);
         }
         z+=1;
     }
     // Return is converting decimal to hexadecimal
     document.getElementById('result').innerHTML = number.toString(16);
}

function hextobin()
{
     mybin = "";
     /// Converting to decimal value and geting ceil of decimal sqrt
     myhex = document.getElementById('hex').value;
     mydec = parseInt(myhex, 16);
     i = Math.ceil( Math.sqrt(mydec) );
     while(i >= 0)
     {
         if(Math.pow(2, i) <= mydec){
             mydec = mydec-Math.pow(2, i);
             mybin += "1";
         }else if(mybin != "")
             mybin = mybin + "0";
             i = i-1;
         }
         document.getElementById('result').innerHTML = mybin;
}
