<<True. But if you know that you are going to need larger intermediate  
results, then I think it is wiser to declare                          
                                                                      
   type Real_Base is digits 7;                                        
   subtype Real is Real_Base range 0.0 .. 1.0;

Mats, you are confused, the base type (and hence the range of intermediate
results) is always unconstrained, so that if you write:

   subtype Real is digits 7 range 0.0 .. 1.0;

as in the original result, you will still get an unconstrained 7 digit
base type.
