abstract final class Float extends AnyVal

Float , a 32-bit IEEE-754 floating point number (equivalent to Java’s float primitive type) is a subtype of scala.AnyVal. Instances of Float are not represented by an object in the underlying runtime system.

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