It is more of a convenience in declaring decimal fixed point types than 
any inherent difference once the types are created.

type Dollars is digits 9 delta 0.01;

on most machines should produce exactly the same type as:

type Dollars is delta 0.01 range -2.0**31/100..2.0**31/100;
for Dollars'Small use 0.01;

But if you are doing financial work it is much clearer.  (It says I want 
a type that corresponds to Cobol +9999999.99.
