//! Finnish (`fi`): the bare-tag alias of [`fi_fi`](crate::fi_fi).
//!
//! `fi` resolves to `fi-FI`, currently the only Finnish variant this crate
//! implements. It exists so the language is reachable without a region
//! subtag; it is not a claim that `fi-FI` speaks for every Finnish-speaking
//! region. Cardinal and ordinal are `fi_fi`'s own functions. Currency is the
//! one form a bare tag can't forward untouched: a language has no country to
//! take a default currency from, so [`to_currency`] takes the currency
//! explicitly.
//!
//! ```
//! use n2words::{fi, Currency};
//!
//! assert_eq!(fi::to_cardinal(42)?, "neljäkymmentäkaksi");
//! assert_eq!(fi::to_ordinal(42)?, "neljäkymmentätoinen");
//! assert_eq!(
//! fi::to_currency(42.5, Currency::EUR)?,
//! "neljäkymmentäkaksi euroa viisikymmentä senttiä"
//! );
//! # Ok::<(), n2words::Error>(())
//! ```
