    function SameValue(const A: Extended; const B: Extended) : Boolean
                  ;  overload; overload;

    function SameValue(const A: Double; const B: Double) : Boolean
                  ;  overload; overload;

    function SameValue(const A: Single; const B: Single) : Boolean
                  ;  overload; overload;

    function SameValue(const A: Extended; const B: Extended; 
                  Epsilon: Extended) : Boolean;  overload; overload;

    function SameValue(const A: Double; const B: Double; Epsilon: Double)
                   : Boolean;  overload; overload;

    function SameValue(const A: Single; const B: Single; Epsilon: Single)
                   : Boolean;  overload; overload;

    Description

    SameValue returns True if the floating-point values A and B are the same, i.e. whether the absolute value of their their difference is smaller than Epsilon. If their difference is larger, then False is returned.

    If unspecified, the default value for Epsilon is 0.0.
