# RealFloat, LongRealFloat, and ExtendedFloat

The interfaces `RealFloat`, `LongRealFloat`, and `ExtendedFloat` define operations that depend on the floating-point representation. Each one is an instance of a generic interface `Float`: floating-point operations

    INTERFACE RealFloat = Float(Real) END RealFloat.
    INTERFACE LongFloat = Float(LongReal) END LongFloat.
    INTERFACE ExtendedFloat = Float(Extended) END ExtendedFloat.
