Attachted I made a little demo programm which shows the problem. My output 
is :
fnCalc1:1.49557e-52
fnCalc2:1.49557e-52
fnCalc2 + 0 :1.49557e-52
fnCalc3:0
Watch this!! 0 
Watch this!! 1.49557e-52

The line >>Watch this!! 0<< should be  >>Watch this!! 1.49557e-52<< at least 
in my mathematical opion. 

Ok, I donot know if my construct with the class Real is a possibile good 
design. I wanted to have an easy possibility to switch from built-in-double 
type to a class type with higher precision. 

Another problem is why I come (in my original programm) to a Real value-type 
of cl_SF while I only use the Real base class with cl_float() function as in 
the demo. But this is for next mailings here.

Thanks for any hint.
