Shared types

Fields typed with one of these names refer to it.

Amount (string): A monetary amount as a decimal string, fixed to the currency's scale — two fraction digits for most supported currencies, none for JPY, e.g. "1000.00" or "1000" for JPY. Never a JSON number. Report figures may be negative; a journal line's debit and credit are always non-negative, with "0.00" ("0" for JPY) on the side the line is not on.
Currency (string): An ISO 4217 alphabetic currency code — a ledger's own functional currency. The supported set is additive, so do not treat it as closed.

Errors
