FAQs
What's the largest number supported?
Up to 10^15 - 1 (quadrillions in short scale). For larger numbers in everyday use you'd switch to scientific notation anyway.
Long scale vs short scale?
Defaults to short scale (US and modern UK): a billion is 10^9. Toggle long scale (older British / European) where a billion is 10^12 and 10^9 is a 'milliard'.
How are decimals handled?
Each digit after the point is read individually: 0.42 becomes 'zero point four two'. For currency, switch to currency mode - 12.50 becomes 'twelve dollars and fifty cents'.
What about negative numbers?
Prefixed with 'minus' or 'negative' (toggle). -3 becomes 'minus three' or 'negative three' depending on preference.
Does it handle other currencies?
Currency mode supports USD (dollars / cents), GBP (pounds / pence), EUR (euros / cents) and INR (rupees / paise) by default - pick the symbol from the dropdown.
