Frequently asked questions
How large a number can I enter?
Numbers up to 999 quintillion (18 digits) are supported, which covers any realistic amount. Larger values show an error.
How are decimals written?
In plain mode, decimals are spelled digit by digit (e.g. 12.5 = Twelve point Five). In currency mode they become cents (e.g. Twelve Dollars and Fifty Cents).
Why does currency mode say 'Even'?
When an amount has no cents, 'and 00/100' is implied in banking. This tool appends 'Even' to clarify there is no cent portion, matching common check-writing style.
