Frequently Asked Questions
What is the largest number it can convert?
The tool handles numbers up to the trillions (999,999,999,999,999). For most practical purposes — invoices, checks, contracts — this range is more than sufficient.
Does it support decimal numbers?
Yes. Decimal parts are converted digit by digit after the word "point". For example, 3.14 becomes "three point one four". This matches the standard English convention for reading decimals aloud.
In which language does it output the words?
Currently the output is in English. The number-to-words algorithm follows the American English short scale (million, billion, trillion) which is also used in most international financial contexts.
