you're right, and the results satisfies me only partially.

I would rather try to "unprotect" the "Power" function and modify it: 
It seems that the "Power" function decides to display the result in a
fractional form if the second argument is numerical. In fact,
  Power[z, -2 x]
  Power[z, -Sqrt[2]]
  Power[z, -Pi]
are all diplayed in an exponential form, whereas
  Power[z, -56789]
  Power[z, -N[Sqrt[2]]]
  Power[z, -N[Pi]]
are all diplayed in a fractional form.

Do you know if it is possible to accés the function?
