💡 Example Conversions
Example 1: Binary to Decimal
- Input:
10101 - Output:
21
Explanation:1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰ = 16 + 0 + 4 + 0 + 1 = 21
Example 2: Decimal to Binary
- Input:
45 - Output:
101101
Explanation:
Divide 45 repeatedly by 2 and write the remainders in reverse order:45 ÷ 2 = 22 R1 → 22 ÷ 2 = 11 R0 → 11 ÷ 2 = 5 R1 → 5 ÷ 2 = 2 R1 → 2 ÷ 2 = 1 R0 → 1 ÷ 2 = 0 R1
Reverse remainders: 101101

- Digits: 0, 1
- Each digit represents a power of 2.
Decimal System (Base-10)
This is the standard system for denoting integer and non-integer numbers.
- Digits: 0 through 9
- Each digit represents a power of 10.
🛠 Behind the Scenes: How the Calculator Works
Without diving into HTML or CSS, the core functionality relies on JavaScript to:
- Read user input
- Validate binary (only 0s and 1s) or decimal (non-negative integers)
- Use built-in JavaScript functions like
parseInt(binary, 2)and.toString(2)for conversion - Display results dynamically within the webpage
