How this service works
A whole number as Spanish words (cardinal, ordinal 1-100), gender, un/uno apocope, long scale (mil millones, un billón).
Output
Returns the cardinal word form (e.g. 'veintiún' or 'uno'), the ordinal word form and figure for numbers 1–100, gender applied, apocope variant (un/uno), long-scale naming (mil millones, un billón), plus a summary, disclaimer, and optional degraded/reasons flags.
Example use cases
Legal document number spelling
“I need to write the amount 250,000 in full Spanish words for a contract — please give me both the masculine and the feminine cardinal forms.”
Ordinal ranking in Spanish
“How do you say 42nd in Spanish? I need both the word and the figure notation, like '42.º', for a ranked list I'm publishing.”
Long-scale billion notation
“What is 2,000,000,000 written out in Spanish words? I want to make sure I'm using the correct long-scale term (mil millones vs un billón) and the right masculine form.”
