Check that each amount can exist in the currency it names
Check that each amount can exist in the currency it names. Reports an amount needing more decimal places than its currency has, where a currency with no sub-unit cannot hold a fraction at all. Also reports an amount that arrived as a JSON number rather than a decimal string, since a binary double cannot hold most two-place decimals exactly, so the digits may already differ from what was written.
