They do not own anything, they're simply thin wrappers on top of the 
pointer, and you can construct them from the pointer and whatever 
information you need as well.

That way the user does not need to allocate his memory with dynamic 
memory allocation -- or even with your type -- to run your arbitrary 
precision algorithms.
