Formule et méthodologie

Recursive grouping: split number into groups of 3 digits from right. Convert each group: hundreds + tens + ones. Group names: thousand, million, billion, trillion, quadrillion. Ordinal: append "th" with irregular forms (first, second, third). Currency: dollars and cents. Negative: prepend "negative." Decimal: "and" + decimal portion as fraction.

Questions fréquentes

Write the dollar amount in words, then "and" then the cents as a fraction over 100. Example: $1,234.56 becomes "One thousand two hundred thirty-four and 56/100." The word "and" should only appear before the cents — not between hundreds and tens ("one hundred twenty-three," not "one hundred and twenty-three" for check writing). End with "dollars."
Cardinal numbers count quantity: one, two, three. Ordinal numbers indicate position or rank: first, second, third. Cardinals are used in most contexts (I have 3 cats). Ordinals are used for rankings, dates, and sequences (the 5th floor, March 3rd, the 2nd place finisher). The conversion rules differ: "one" becomes "first," "two" becomes "second," "three" becomes "third," then pattern-based for the rest.
