Functions to implement the number system rule-based-number-format rules of CLDR.
These rules are defined only on the "root" locale and represent specialised
number formatting.
The standard public API for RBNF is via the `Cldr.Number.to_string/2` function.
The functions on this module are defined at compile time based upon the RBNF rules
defined in the Unicode CLDR data repository. Available rules are identified by:
iex> #{inspect(__MODULE__)}.rule_sets("root")
[:tamil, :roman_upper, :roman_lower, :hebrew_item, :hebrew_0_99, :hebrew,
:greek_upper, :greek_lower, :georgian, :ethiopic_p1, :ethiopic,
:cyrillic_lower_1_10, :cyrillic_lower, :armenian_upper, :armenian_lower]
A rule can then be invoked on an available rule_set. For example
iex> #{inspect(__MODULE__)}.roman_upper(123, "root")
"CXXIII"
This call is equivalent to the call through the public API of:
iex> #{inspect(unquote(backend))}.Number.to_string(123, format: :roman)
{:ok, "CXXIII"}
