Frequently asked questions
How large a number can it spell out?
It handles everyday numbers through the millions and billions using the standard short-scale names. Enter a whole number and it returns the full written form, grouped into thousands, millions and so on the way the number is normally read aloud.
Can it write out decimals or currency amounts?
It is built for whole numbers, which covers most cheque and document needs. For an amount of money, spell out the whole part with the tool and then add the currency and any cents yourself, for example two hundred fifty dollars and fifty cents.
Is my data sent anywhere?
No. The number is converted in your browser, so nothing you type is sent to or stored on a server.
