   Yes.  But you can switch between different sizes that all fit into a   
   cell, or between different memory sizes of floats without changing the   
   rest of the code.

   That's just as for reading the value-flavoured field; if a field   
   pushes one cell, TO to the field also consumes one cell; likewise for   
   float fields.
