Examples
Formula:
Each Octal Digit → 3-bit Binary
Example 1: Octal: 46
→ 4 = 100, 6 = 110
→ Binary = 100110
Example 2: Octal: 725
→ 7 = 111, 2 = 010, 5 = 101
→ Binary = 111010101
Example 3 (with fraction): Octal: 3.4
→ 3 = 011, 4 = 100
→ Binary = 011.100

Additional Information
A Unique Explanation for the Octal to Binary Converter:
The octal system (base-8) was historically favored in computing due to its simplicity in representing 3-bit binary chunks.
Each octal digit directly corresponds to three binary digits, making the conversion process seamless and efficient.
Example:
Octal 71
→ 7 = 111, 1 = 001
→ Binary = 111001
This conversion is especially helpful when translating compact instructions or permissions into binary logic for further computation.
