The type of a currency is identified using ISO-4217. This is a three-letter string like “USD” or “EUR”. The value of a currency is represented in micros. For USD, $5.50 is encoded as 5.50*1e6, or 5,500,000. To represent a “whole value”, you need to multiply the local micro by 1e6 (1_000_000) for all currencies.
