  AFAIK there's no difference between scales smaller than 1 and bigger than
1 when dealing with floats. It just changes the sign of the exponent. The
precision of the mantissa doesn't change anywhere.
  You have to go to scales smaller than something like 10^-30 in order to
reach serious precision limits.
