Spelling Decimal Numbers
In US English, the decimal point is read as the word point, and every digit after the point is read individually.
Rules
- Read the whole-number part normally (three, ninety-nine).
- Say point for the decimal separator.
- Read each digit after the point one at a time — not as a whole number.
- A leading zero is said as zero (US) or nought / oh in some dialects.
- Money is an exception: $3.14 is usually said as three dollars and fourteen cents, not three point one four dollars.
Examples
| Input | In words |
|---|---|
| 3.14 | three point one four |
| 0.5 | zero point five |
| 2.718 | two point seven one eight |
| 99.99 | ninety-nine point nine nine |
| 0.005 | zero point zero zero five |
