      // cast the decimal into a string
      aString string = aDecimal;
  
            SysLib.writeStdout('Rounding successfull= ' +
  aString);
    onException(ae AnyException)
     SysLib.writeStdout(ae.message);
    end
   end
  
      private function thisFunctionDoesNotWork()
          try
          // rounding into a string
              aDecimal       decimal(4,2) = 1.1;
           aString        string = MathLib.round(aDecimal, -1);
               SysLib.writeStdout('Rounding successfull= ' +
  aString);
  
          onException(ae AnyException)
              SysLib.writeStdout(ae.message);
          end
      end
  end
  
  
  After selecting each button in the RUI preview the first
  rounding returns correctly and the second with the string
  assignment fails ie:
  Rounding successful= 1.10
  [CRRUI2078E] Math error: round() - Rounding necessary
