Question

How to convert int to binary in array with Node.js

Answer 1

function toBinary(n, binaryNum)  { 
    let i = 0; 
    while (n > 0) { 
        binaryNum[i] = n % 2; 
        n = Math.floor(n / 2); 
        i++; 
    } 
    
    return i;
} 


let binaryNumber = new Array(32); 
const a = 23;
let s = "";

let i = toBinary(a, binaryNumber);
for (let j = i - 1; j >= 0; j--) {
    s += binaryNumber[j];
}
console.log(s);
 
const b = 9863;

s = "";
i = toBinary(b, binaryNumber);
for (let j = i - 1; j >= 0; j--) {
    s += binaryNumber[j];
}
console.log(s);
