- Ordinals are shown only for integers of zero or more, not for decimals or negative numbers.
- The check format is shown only for numbers of zero or more with at most two decimal places; the fraction is written as 50/100. It is not shown for three or more decimals or for negative numbers.
- The Japanese reading uses the common forms: 4 is よん, 7 is なな and 9 is きゅう. Alternative readings such as し, しち and く are not produced.
- Follow the format required by your bank or the recipient when writing checks and contracts.
Glossary
Cardinal vs. ordinal
Cardinal numbers (one, two, three) express quantity; ordinal numbers (first, second, third) express position. Only the last word becomes ordinal, so 21st is twenty-first.
Check format (and 50/100)
US checks show the amount in both digits and words. The cents are written as a fraction of 100, such as "and 50/100", which makes the amount harder to alter.
British "and"
British English reads 101 as "one hundred and one", adding "and" after the hundreds or thousands. American English omits it ("one hundred one").
FAQ
How do I write an amount on a check?
Enter the amount and use the "Check / contract amount" row. It shows the whole part in words followed by the cents as a fraction of 100, such as "and 50/100 dollars". You can pick dollars, pounds or euros. It is not shown for amounts with three or more decimals or for negative numbers.
Is 101 "one hundred one" or "one hundred and one"?
American English omits "and" (one hundred one) and British English includes it (one hundred and one). Toggle the British style option to switch. The "and" before the cents on a check is included in both styles.
Does it show ordinals like 1st, 2nd and 3rd?
For integers of zero or more it shows the ordinal in words (first, twenty-first) and in digits (21st). 11, 12 and 13 become 11th, 12th and 13th. Decimals and negative numbers have no ordinal.
Does the Japanese reading include し, しち and く?
No. 4 is always よん, 7 is なな and 9 is きゅう. Sound changes such as さんびゃく, ろっぴゃく, はっせん and いっちょう are applied.
How large a number can it convert?
Up to 36 integer digits (decillions in English) and 30 decimal digits. Longer input shows a "too long" error.
