Spell integers and decimal digits as English words, with US or British-style wording.
Supported range and style
The converter reads the whole-number part in groups up to quadrillions and reads decimal digits one by one after “point.” It does not add currency names or cheque-specific wording.
Formatting note
English number wording varies by region and document style. Use the US/British option as a general language choice, then follow any specific legal, banking or house-style rules that apply to your document.
