FAQs
What is the largest number it handles?
Any whole number below one quadrillion — that is up to 999,999,999,999,999. Larger values return a friendly message asking for a smaller number.
Does it handle decimals?
No. It converts whole numbers only. For amounts like £12.50, convert the pounds and pence separately.
Why is there no “and” in the output?
It uses the plain international style without “and” (for example, “one hundred twenty-three”). This keeps the wording consistent and unambiguous.
Can I use the words on a cheque?
The output is capitalised and cheque-friendly, but always double-check important documents yourself before submitting them.
