//! Norwegian Bokmål (`nb`): the bare-tag alias of [`nb_no`](crate::nb_no).
//!
//! `nb` resolves to `nb-NO`, currently the only Norwegian Bokmål variant this crate
//! implements; it exists so the language can be named without a region
//! subtag, not as a claim that `nb-NO` speaks for every Norwegian Bokmål-speaking
//! region. Cardinal and ordinal are `nb_no`'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::{nb, Currency};
//!
//! assert_eq!(nb::to_cardinal(42)?, "førti-to");
//! assert_eq!(nb::to_currency(42.5, Currency::NOK)?, "førti-to kroner og femti øre");
//! # Ok::<(), n2words::Error>(())
//! ```
