For an example of when such a representation may be useful,
Numberphile had a video on the number 10^10^10^10^10^1.1:

To give an idea of the accuracy of the calculations for this kind
of number, the units for that number, in a scientific paper, is
given as 'Planck times, millennia, or whatever'. A factor of
10^55 is inconsequential here. That would never be the case for
floating points numbers, where the accuracy is always a certain
percentage of the absolute value.
