 * - 10⁶ = millón
 * - 10⁹ = mil millones (thousand millions)
 * - 10¹² = billón
 *
 * Spanish-specific rules:
 * - Gender agreement: uno/una, veintiuno/veintiuna, hundreds
 * - Special twenties: veinte, veintiuno, veintidós, ... veintinueve
 * - "y" conjunction: treinta y uno (only 30-99 with ones)
 * - "cien" for exact 100, "ciento/cienta" otherwise
 * - Irregular hundreds: quinientos, setecientos, novecientos
 * - "un" before millón (not "uno"), omit before mil
