javascript number to binary string 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: number to binary javascript

const convertNumberToBinary = n => {
    // convert number to binary
    let binary = (n >>> 0).toString(2).split('').sort().join('');
    // convert binary to number
    let number = parseInt(binary, 2);
    // return result
    return number;
}

Example 3: javascript convert to and from binary

/* From decimal to binary (similar fo rother base) */
const num = 7;
num.toString(2); // output: "111"

/* From binary (similar fo rother base) to decimal */
parseInt("111", 2); // output: 7

Example 4: 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 5: 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
