abstract final class Double extends AnyVal

Double , a 64-bit IEEE-754 floating point number (equivalent to Java’s double primitive type) is a subtype of scala.AnyVal. Instances of Double are not represented by an object in the underlying runtime system.

There is an implicit conversion from scala.Double => scala.runtime.RichDouble which provides useful non-primitive operations.
