Frequently asked questions
What is the biggest number this supports?
Up to 999 trillion (999,999,999,999,999), positive or negative. Anything larger is rejected with a clear message — this keeps every conversion exact, since bigger values lose precision in floating-point math.
How are decimals read out?
Digit by digit after the word “point” — so 3.14 becomes “three point one four”, exactly how you would read it aloud.
How are negative numbers handled?
With a leading “minus” — -42 becomes “minus forty-two”. (Negative zero is just “zero”.)
