⚙️ How the Converter Works

1. Enter a number in the input field.
2. The calculator checks if the value is valid.
3. The number is split into groups of three digits (hundreds).
4. Each group is converted into words (e.g., 345 → “three hundred forty five”).
5. Scale names (thousand, million, etc.) are added based on position.
6. If decimals exist, they are converted separately and appended.
7. If the number is negative, the word “minus” is added at the beginning.
8. The final result is displayed instantly.

All processing is done using JavaScript in real time, ensuring fast and accurate number spelling.

📌 Example

Suppose you enter:

125034

The calculator converts it into:

one hundred twenty five thousand thirty four

The number is broken into groups (125 and 034), converted separately, and combined with the scale name “thousand”.
