package Interchange_Float is

    -- This package provides primitives to convert Floats
    -- to and from IEEE floating point format.  Its only
    -- client is package Interchange.  This package exists
    -- to simplify porting: if you supply the bodies to
    -- these procedures, Interchange will do the right thing.

    -- IEEE single-precision format:
    type Float is new Byte_Defs.Byte_String (1 .. 4);  
    function Convert (X : Interchange_Float.Float)  
                     return Interchange_Defs.Float;  
    function Convert (X : Interchange_Defs.Float)  
                     return Interchange_Float.Float;
