The ledger nets every currency in hundredths, and the settlement handed those
hundredths out as they were. For a currency shown without decimals the panels
then rounded each balance and flow on its own: 10,000 KRW three ways read
+6,667 / -3,333 / -3,333, two flows of 3,333 sat under "You're owed 6,667",
and Settle booked 3,333.34 won.
The balances, flows and final budget lines are now allocated by largest
remainder in whole steps of the display currency (whole won or yen, unchanged
for two and three decimal ones), so the shown set adds up to zero and the flow
amount Settle sends is the whole amount on the row. The ledger, stored rows
and manual settlements are untouched. REST and the MCP settlement summary
share the same method.
