Type number words for decimal values fast. Check normalized phrases, place values, and parsing notes. Export results, compare examples, and verify tricky conversions easily.
| Written Input | Decimal Output | Parsing Note |
|---|---|---|
| one hundred twenty three point four five | 123.45 | Whole words create 123, then decimal digits become 45. |
| negative seven thousand point zero nine | -7,000.09 | The sign is negative and the decimal keeps the leading zero. |
| two million sixteen | 2,000,016 | The remaining group adds to the larger million scale. |
| forty-two dot six | 42.6 | Hyphen normalization allows forty-two to parse correctly. |
| one hundred and eight point oh five | 108.05 | The filler word is removed and “oh” maps to zero. |
| nine hundred ninety nine thousand nine hundred ninety nine | 999,999 | Large groups combine through scale multiplication and addition. |
The calculator converts written numbers by splitting the phrase into a whole-number part and an optional decimal part. It then applies scale multiplication and positional decimal values.
Whole Value = Σ(group value × scale) + remaining group
Decimal Fraction = Σ(digitᵢ × 10^-i)
Final Decimal = sign × (Whole Value + Decimal Fraction)
Example: “one hundred twenty three point four five” becomes 123 + (4×10^-1) + (5×10^-2) = 123.45.
It converts written number phrases into decimal values. Examples include whole numbers, negatives, and decimal expressions such as “three point one four” or “negative six thousand point zero two.”
Yes. It supports hundred, thousand, million, billion, trillion, and quadrillion. These scale words are multiplied by their group values, then added into the final whole-number result.
Yes. With hyphen normalization enabled, entries like “forty-two” are converted into standard tokens before parsing. This helps the tool read common written styles more reliably.
Strict mode rejects suspicious word order, especially repeated or badly ordered scale words. It is useful when you want tighter validation instead of permissive interpretation.
Yes. Inputs like “point zero five” keep both decimal digits, producing 0.05. This matters when written decimal words include zeros before a later nonzero digit.
Yes, when the related option is enabled. That allows phrases like “point oh seven” to parse as 0.07, which matches many spoken-number patterns.
No. This tool is designed for decimal-style wording that uses point or dot. Common fractions should be rewritten in decimal word form before conversion.
The exact result preserves all parsed decimal digits. The rounded display applies your chosen precision, which is helpful when preparing reports, tables, or cleaner exported summaries.
