You're seeing just the function resolve_currencies, go back to MyApp.Cldr.Number module for more information.

resolve_currencies(list, options \\ [])

Resolve curencies from strings within a list.

Arguments

list is any list in which currency names and symbols are expected
options is a keyword list of options

Options

:locale is any valid locale returned by Cldr.known_locale_names/1 or a Cldr.LanguageTag struct returned by Cldr.Locale.new!/2 The default is MyApp.Cldr.get_locale()
:only is an atom or list of atoms representing the currencies or currency types to be considered for a match. The equates to a list of acceptable currencies for parsing. See the notes below for currency types.
:except is an atom or list of atoms representing the currencies or currency types to be not considered for a match. This equates to a list of unacceptable currencies for parsing. See the notes below for currency types.
:fuzzy is a float greater than 0.0 and less than or equal to 1.0 which is used as input to String.jaro_distance/2 to determine is the provided currency string is close enough to a known currency string for it to identify definitively a currency code. It is recommended to use numbers greater than 0.8 in order to reduce false positives.

Notes

The :only and :except options accept a list of currency codes and/or currency types. The following types are recognised.

If both :only and :except are specified, the :except entries take priority - that means any entries in :except are removed from the :only entries.

:all, the default, considers all currencies
:current considers those currencies that have a :to date of nil and which also is a known ISO4217 currency
:historic is the opposite of :current
:tender considers currencies that are legal tender
:unannotated considers currencies that don't have "(some string)" in their names. These are usually financial instruments.
