How it is calculated
Numbers are read in groups: millones, mil, then hundreds. 100 alone is cien and becomes ciento before another number, 16 to 29 are single words such as dieciséis and veintidós, and uno shortens to un before mil and millón. A thousand million is mil millones.
Example
Inputs: Number = 1234567. Result: In Spanish: un millón doscientos treinta y cuatro mil quinientos sesenta y siete; Formatted number: 1 234 567.
Limits and caveats
- Forms are for masculine nouns; feminine nouns change some words, such as una and doscientas.
- The limit is below one billón, which is 10 to the power 12.

Cien is 100 on its own and before mil or millones, as in cien mil; ciento is used before a smaller number, as in ciento uno.

Veintiuno shortens to veintiún before mil and millón, and the accent on u follows the Royal Spanish Academy rules.
Does billón mean a billion?
