📌 What is an Octal Number?
The **octal number system** is a base-8 numeral system that uses eight symbols: **0-7**. It is commonly used in computing for representing binary numbers in a more compact form.
Example: The octal number **7** is represented as **111** in binary.
📌 Methods to Convert Octal to Binary
- Substitution Method: Replace each octal digit with its three-bit binary equivalent.
- Direct Conversion: Use an octal-to-binary conversion chart for reference.
- Using Built-in Functions: Many programming languages provide built-in functions for conversion.
📌 Examples of Octal to Binary Conversion
| Method | Example | Solution |
|---|---|---|
| Substitution Method | 25 | 2 → 010, 5 → 101 → **010101** |
| Direct Conversion | 63 | 6 → 110, 3 → 011 → **110011** |
| Built-in Functions | 17 | parseInt(“17”, 8).toString(2) = **001111** |
❓ FAQs
Q1: What are the advantages of using octal over binary?
✅ The octal system is more compact and easier to read compared to binary, which makes it useful in computing. Additionally, each octal digit represents exactly three binary digits, simplifying conversion.
Q2: How is octal different from decimal and binary?
✅ The octal system is base-8, meaning it uses digits from 0 to 7, whereas decimal is base-10 and binary is base-2. Octal is often used as a shorthand for binary in digital electronics.
Q3: Can I convert fractional octal numbers to binary?
✅ Yes, you can convert fractional octal numbers to binary by converting each octal digit separately. The whole number part and the fractional part are converted independently.
Q4: Why is octal commonly used in programming?
✅ Octal is widely used in programming because it provides a shorter way to represent long binary numbers. Many file permissions and memory addresses in Unix-based systems use octal notation.
Q5: Are there any real-world applications of octal numbers?
✅ Yes, octal numbers are used in computing, digital circuit design, and even aviation navigation systems. Their ability to simplify binary representation makes them useful in many technical fields.
