How to convet decimal number base-12 number in JavaScript

Answer 1

// Converts a decimal number to base-12 and returns it as a string
function decimalToBase12(decimalNumber) {
    if (decimalNumber === 0) {
        return "0";
    }

    const digits = "0123456789AB"; // Base-12 digits (A = 10, B = 11)
    const base12 = [];

    while (decimalNumber > 0) {
        const remainder = decimalNumber % 12;
        base12.push(digits[remainder]);
        decimalNumber = Math.floor(decimalNumber / 12);
    }

    // Reverse to get the correct order
    return base12.reverse().join('');
}

let decimalNumber = 100;
let base12Number = decimalToBase12(decimalNumber);
console.log(`Base-12 representation: ${base12Number}`);

decimalNumber = 19621;
base12Number = decimalToBase12(decimalNumber);
console.log(`Base-12 representation: ${base12Number}`);
