# Growing factor computation. This formula is used to compute
# the increment is memory allocation in terms of the memory
# already allocated, but avoiding a zero or a large factor.
# The real number in the formula represents the fraction to grow,
# and it should be greater than zero and less than one, although
# the formula takes care of out of range values.
