Boolean is the shared name used by Elements on all platforms and languages for the type used to represent a boolean value of either true or false. Booleans are value types.

The Boolean type is defined in the RemObjects.Elements.System namespace – which is in scope by default and does not have to be used/imported manually. However, the namespace name can be used to prefix the type names, where necessary, to avoid ambiguities.

In C#, the bool keyword can also be used to refer to this type, and Swift defines the Bool aliases in the Swift namespace via the Swift Base Library.
