local p = {}

-- For use by other scripts. Takes arguments:
-- - 1: string or number, value to convert
-- - forcenum: string for Template:Yesno, forces a result in digits for all n ≥ 10.
-- - formating options for spellnum: zero, adj, ord, us
-- WARNING: zero defaults to blank which is probably not what you want.
