| <p>The standard type Real represents the mathematical concept of real. | |
| Note that UnlimitedNatural is a subclass of Integer and that Integer is a subclass of Real, | |
| so for each parameter of type Real, you can use an unlimited natural or an integer as the actual parameter. | |
| Real is itself an instance of the metatype PrimitiveType (from UML).</p> | |
