Number to Words
A number-to-words converter spells a figure out in English words: type 1234 and it writes one thousand two hundred and thirty-four. Currency mode turns $1,250.75 into one thousand two hundred and fifty dollars and seventy-five cents; Ordinal mode turns 21 into twenty-first. Decimals are read digit by digit, so 3.14159 becomes three point one four one five nine.
Write numbers as English cardinal words, ordinals or currency amounts.
English output only, on every interface language. Maximum 21 integer digits and 100 fractional digits. No grouping separators. Ordinals require an integer. Currency uses two decimal places, half-up away from zero (USD 1.999 → two dollars); JPY retains the legacy yen/sen convention, not modern cash rounding.
