Frequently Asked Questions
What numbers are supported?
The tool supports integers (positive and negative) and decimal numbers up to the range supported by JavaScript's Number type - that covers values up to approximately 9 quadrillion. For very large numbers, consider scientific notation inputs if needed.
Does it support decimals?
Yes. In Cardinal mode, decimals are written out (e.g., 1.5 → "one point five"). In Currency mode, the decimal portion is treated as cents (e.g., 1.50 → "one dollar and fifty cents").
What is Currency mode?
Currency mode (available for English Cardinal) formats the output for check writing - the integer part is expressed in dollars and the decimal part in cents. For example, 1250.75 becomes "one thousand two hundred fifty dollars and seventy-five cents." This matches the format required by most US banking institutions.
What languages are available?
This tool currently supports English (en), Spanish (es), and German (de). These cover the most common use cases for international finance and legal documents.
What is the difference between Cardinal and Ordinal?
Cardinal numbers express a quantity: one, two, three. They are used for amounts on checks and invoices. Ordinal numbers express a position: first, second, third. They are used for dates (the twenty-third of June), rankings, and chapter headings.
Is my data stored or sent anywhere?
No. All conversion runs entirely in your browser using JavaScript. Your numbers are never transmitted to any server, stored in a database, or shared with any third party. It is safe to enter confidential financial figures.

How do I spell out large numbers like one million or one billion?
