Supports integers, decimals, and negative numbers up to the trillions.
How It Works
Enter any number and it is instantly converted to English words:
- Integer part — Split into groups of three digits, each group converted using ones, tens, and hundreds, then combined with scale words (thousand, million, billion, trillion).
- Decimal part — Each digit after the decimal point is spelled out individually (e.g., 0.25 becomes "zero point two five").
- Negative numbers — Prepended with the word "negative".
