This raises a question I've been wondering about for a while: When
we say that a float (or char) gets converted to a double (or int) in
an expression, what exactly constitutes an expression? Is a single
value on the RHS of an assignment operator an "expression" for
conversion purposes? Or is at least one operator required? If
I do a "f1=f2", does it first convert f2 to double and then back 
to float in order to do the assignment? How about "c1=c2" for chars?
