No there is no REAL computer. An "analog" computer is
really digital, the resolution is a function of the
charge on an electron and the supply voltage used in a
particular application.

Thank you.
Last week, I was explaining to one of my classes the
differences between
Floating Point and Real.
A REAL computer (if there were such - analog??)
would have infinite
numbers between 1 and 2. A Floating Point system
only has about 8
million, and doesn't have any odd numbers above
about 16 million.
Double precision has substantially more, but still
quite clearly
finite.
