display-to-decimal - Use toDecimal for display strings, not toSnapshotdisplay-no-currency-symbols - Dinero.js does not format currency symbols; compose with Intl.NumberFormatlocale-intl-formatter - Build reusable formatters with Intl.NumberFormatlocale-multilingual - Create locale-parameterized formatters for multilingual sitesserialization-snapshot - Use toSnapshot for transport and storage, not displayserialization-bigint-json - BigInt Dinero objects require a custom JSON replacernondecimal-to-units - Use toUnits for non-decimal currencies, not toDecimalRead individual rule files for detailed explanations and code examples:
