How it works
The number is split into groups of three digits (thousands, millions, billions) and each group is spelled out, then joined.
Worked example
1234. = One thousand two hundred thirty-four.
Common mistakes
- Expecting currency words — this spells the plain number, not '… dollars and cents'.
- Very long numbers beyond a trillion aren't supported.
Frequently asked questions
What is this used for?
Writing amounts in words for cheques, contracts and invoices, where the spelled-out figure prevents tampering.
Does it handle decimals and currency?
Yes — it writes whole numbers and can express cents or decimals in words for clear, unambiguous documents.
How are decimals handled?
After 'point', each digit is read individually — 3.14 becomes 'three point one four'.
