Frequently asked questions
- How do I write an amount on a check?
- Use the check-writing style: the dollars in words, then “and”, then the cents as a fraction of 100 — e.g. “One thousand two hundred and 56/100”. Draw a line through any leftover space to prevent alterations.
- Why write amounts in words at all?
- Words are much harder to alter or misread than digits, so checks, contracts, and legal documents traditionally state amounts both ways; when they conflict, the words usually prevail.
- How large a number can it handle?
- Up to about 9 quadrillion (JavaScript's safe-integer limit), which covers any realistic monetary or document use.
