Decimal to Binary

🔍 Introduction: What is a Decimal to Binary Converter?

A Decimal to Binary Converter is a digital tool that instantly transforms a base-10 number (decimal) into a base-2 number (binary). It’s widely used by students, software developers, data scientists, and electronics engineers to simplify calculations and understand how computers process numbers.

Whether you’re studying computer science, preparing for coding interviews, or working on a digital logic design project, converting numbers from decimal to binary is a fundamental skill you must master.

💡 Why is Binary Important in Computing?

Binary numbers are the foundation of all modern computing systems. Every piece of data — from the text you type to the videos you stream — is stored and transmitted as binary digits (0s and 1s).

Why?

Because binary is the only language digital circuits and processors understand. Voltage levels in circuits are interpreted as ON (1) and OFF (0), making binary the universal machine code.

⚙️ How the Decimal to Binary Converter Works

The converter uses a mathematical process known as repeated division by 2 to convert the number.

🔢 Example:

Convert 25 to binary:

• 25 ÷ 2 = 12 remainder 1

• 12 ÷ 2 = 6 remainder 0

• 6 ÷ 2 = 3 remainder 0

• 3 ÷ 2 = 1 remainder 1

• 1 ÷ 2 = 0 remainder 1

Now read the remainders in reverse order:

👉 11001

So, 25 (decimal) = 11001 (binary)

❓ Frequently Asked Questions (FAQs)

📌 1. What is the difference between decimal and binary?

Decimal is base-10 (0–9), while binary is base-2 (only 0 and 1). Computers use binary for all operations.

📌 2. How do I manually convert a decimal to binary?

Use repeated division by 2 and write down the remainders in reverse order to get the binary value.

📌 3. Can I convert negative decimal numbers to binary?

Yes! Negative numbers are often represented in binary using Two’s Complement method.

📌 4. Is it possible to convert fractional decimal numbers to binary?

Absolutely. It requires converting both the integer and fractional parts separately using division and multiplication methods.
