## Public predicates

### `currency/5`

Enumerates ISO 4217 active non-fund entries as alphabetic code, numeric code, minor unit, currency name, and entity tuples. The minor unit is either an integer or the atom `na` when the standard lists `N.A.`.

Compilation flags:
`static`
Template:
`currency(Alphabetic,Numeric,MinorUnit,Name,Entity)`
Mode and number of proofs:
`currency(?atom,?integer,?term,?atom,?atom)` - `zero_or_more`

### `fund_currency/5`

Enumerates ISO 4217 active fund entries as alphabetic code, numeric code, minor unit, currency name, and entity tuples. The minor unit is either an integer or the atom `na` when the standard lists `N.A.`.

Compilation flags:
`static`
Template:
`fund_currency(Alphabetic,Numeric,MinorUnit,Name,Entity)`
Mode and number of proofs:
`fund_currency(?atom,?integer,?term,?atom,?atom)` - `zero_or_more`
