   Flop counting:  We count each arithmetic operation (e.g., addition, multiplication) separately.

   For the complex numbers version, note that
       1 complex addition = 2 flops
       1 complex multiplication = 6 flops,
   where we define 1 flop as that for a double precision scalar.  We roughly approximate
   flop counting for complex numbers by multiplying the total flops by 4; this corresponds
   to the assumption that we're counting mostly additions and multiplications -- and
   roughly the same number of each.  More accurate counting could be done by distinguishing
   among the various arithmetic operations.
