JavaScript Program to Converter a Decimal to Binary

Photo Credit to CodeToFun

🙋 Introduction

In the world of programming, converting numbers from one base to another is a common and essential task. One interesting conversion is from decimal to binary. Decimal is the base-10 number system, and binary is the base-2 system.

Converting a decimal number to its binary equivalent involves representing the decimal value using only the digits 0 and 1.

In this tutorial, we'll explore a javascript program that efficiently converts a decimal number to its binary representation.

📄 Example

Let's dive into the javascript code that achieves this functionality.

decimalToBinary.js

Copied

// Function to convert decimal to binary
function decimalToBinary(decimalNumber) {
  let binaryNumber = [];

  // Convert decimal to binary
  while (decimalNumber > 0) {
    binaryNumber.push(decimalNumber % 2);
    decimalNumber = Math.floor(decimalNumber / 2);
  }

  // Print binary number in reverse order
  console.log("Binary equivalent: " + binaryNumber.reverse().join(''));
}

// Driver program
// Replace this value with your desired decimal number
const decimalNumber = 15;

// Call the function to convert decimal to binary
decimalToBinary(decimalNumber);

💻 Testing the Program

To test the program with a different decimal number, simply replace the value of decimalNumber in the main function.

Binary equivalent: 1111

Run the program to see the binary equivalent.

🧠 How the Program Works

1. The program defines a function decimalToBinary that takes a decimal number as input and logs its binary equivalent.
2. Inside the function, it uses an array (binaryNumber) to store the binary digits.
3. It iterates through the process of dividing the decimal number by 2 and pushing the remainder until the decimal number becomes 0.
4. The binary digits are stored in the array and then printed in reverse order to get the correct binary representation.

🧐 Understanding the Concept of Decimal to Binary

Before delving into the code, let's briefly understand the binary number system. In binary, each digit represents a power of 2, starting from the rightmost digit as 2^0, then 2^1, 2^2, and so on.

Converting a decimal number to binary involves repeatedly dividing the decimal number by 2 and recording the remainders in reverse order.

For example, the decimal number 15 is equivalent to the binary number 1111.

🎢 Optimizing the Program

While the provided program is effective, consider exploring and implementing optimizations for handling larger decimal numbers.

Feel free to incorporate and modify this code as needed for your specific use case. Happy coding!
