annual_average BNR annual average ~149
BNR's annual average rate for a year, as ANAF converts foreign income in the D212 ("cursul de schimb mediu anual comunicat de BNR"): the mean of the twelve monthly averages, each the mean of the month's daily rates, to four places, with the monthly values and their day counts. Not the mean of the daily rates, which differs. A year not over yet answers the months so far with complete: false.

convert Convert to or from RON ~329
An amount converted to or from RON at BNR's reference rate, computed exactly and rounded once: to RON is amount x rate / multiplier, from RON amount x multiplier / rate. rate_rule picks the fixing: in_force (the day's, or the last banking day's before it, as rate answers) or last_before (the last one strictly before the day, the rule for an invoice in a foreign currency). Answers the result with the rate, its multiplier and the date BNR published it, so the conversion can be stated. One side must be RON; for two other currencies, convert twice.

|---|---|---|---|
| amount | string | yes | The amount, as a decimal string: "1250.50", "-75". Never a number. |
