Not only, remember: Computer memories can't think in powers of ten.

Yes, but since the representation in computers is based on powers of
two, a certain precision in the dual system, i. e. a fixed amount
of dual places, doesn't correspond with a fixed amount of decimal
places. Thus the rounding while displaying -- just to make it look
prettier. The very minimal additional error is silently accepted.
