int to binary javascript code example

Example 1: javascript convert number to binary

function dec2bin(dec){
    return (dec >>> 0).toString(2);
}

dec2bin(1);    // 1
dec2bin(-1);   // 11111111111111111111111111111111
dec2bin(256);  // 100000000
dec2bin(-256); // 11111111111111111111111100000000

Example 2: convert decimal to binary javascript

var n = 5;
n.toString(2); // "101"

Example 3: javascript convert number to binary representation

// Javascript convert a number to a binary equivalent.
// Syntax: n.toString(radix)
// Note that radix in this syntax is the radix n will become.
let n = 100;
let binary = n.toString(2);
// => 1100100

// Convert a binary number to a radix of 10 equivalent.
// Syntax: parseInt(num, radix).
// Note that radix in this syntax is denoting i's current radix.
let i = 1100100;
let number = parseInt(i, 2);
// => 100

Example 4: how to get binary value of int javascript

const convertNumberToBinary = number => {
    return (number >>> 0).toString(2);
}

Example 5: number to binary javascript

// method one
function convertNumberToBinary (num) {
 return parseInt([...num.toString(2)].reverse().join(''), 2);
}

// methode two
function convertNumberToBinary (num) {
 return parseInt(num.toString(2).slice('').reverse().join(''), 2);
}

// methode three
function convertNumberToBinary (num) {
  let binary = (n >>> 0).toString(2).split('').sort().join('');
  let number = parseInt(binary, 2);
  return num;
}

Example 6: how to convert to binary in javascript

function bin(num) {
    var binn = [];
    var c;
    while (num != 1) {
        c = Math.floor(num / 2);
        binn.unshift(num % 2);
        num = c;

    }
    binn.unshift(1)
    return binn
}
//returns list of binary nos. in order
