HDL_ANT version 2.1
        
        There was a problem with Version 2.0 of HDL_ANT which caused
        output of some calculations to have significant roundoff errors.
        This has been corrected in Version 2.1.  
        
        The problem was caused by using a newer version of the Borland C++
        compiler for HDL_ANT version 2.0.  I took the cautious approach
        of not changing any of the working code from version 1.0, just 
        adding new features.  However, the compiler upgrade changed the
        operation of the C++ function cout.setprecision();  I believe 
        that the newer version compiler implements it properly.  
        
        I did not notice the discrepancy when testing HDL_ANT version 2.0,
        but I certainly have checked version 2.1 more carefully.
        
        Please pass along the new version to those without Internet access.
