convert to binary js 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: 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 3: how to get binary value of int javascript

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

Example 4: string to binary javascript

// string to binary
parseInt(num.toString(2));

// binary to string
parseInt(num.toString(2), 2);

Example 5: DECIMAL TO BINARY CONVERSION javascript

// program to convert decimal to binary
function convertToBinary(x) {
    let bin = 0;
    let rem, i = 1, step = 1;
    while (x != 0) {
        rem = x % 2;
        console.log(
            `Step ${step++}: ${x}/2, Remainder = ${rem}, Quotient = ${parseInt(x/2)}`
        );
        x = parseInt(x / 2);
        bin = bin + rem * i;
        i = i * 10;
    }
    console.log(`Binary: ${bin}`);
}

// take input
let number = prompt('Enter a decimal number: ');

convertToBinary(number);

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
