 6. Views in SQLite are read-only. However, the CAP Java SDK supports some views to be updatable as described in [Updatable Views](../working-with-cql/query-execution#updatable-views).
 7. Foreign key constraints are supported, but are disabled by default. To activate the feature using JDBC URL, append the `foreign_keys=on` parameter to the connection URL, for example, `url=jdbc:sqlite:file:testDb?mode=memory&foreign_keys=on`. For more information, visit the [SQLite Foreign Key Support](https://sqlite.org/foreignkeys.html) in the official documentation.
 8. CAP enables regular expressions on SQLite via a Java implementation. The matching behaviour is an equivalent of the `Matcher.find()` call for the given pattern.
+9. `Decimal` values are stored as IEEE 754 double-precision floating-point numbers on SQLite which allows arithmetic operations to be performed directly in the database. Note, when values can't be represented exactly in this binary floating-point format, they lose some precision.
