How to convet decimal number base-12 number in Node.js

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('');
}

// Run the function with sample inputs
const decimalNumber1 = 120;
const base12Number1 = decimalToBase12(decimalNumber1);
console.log(`Base-12 representation: ${base12Number1}`);

const decimalNumber2 = 17534;
const base12Number2 = decimalToBase12(decimalNumber2);
console.log(`Base-12 representation: ${base12Number2}`);

Base-12 representation: A0
