/* A tight upper bound on number of parts required to hold the
value pow(5, power) is
power * 65536 / (28224 * integerPartWidth) + 1
However, whilst the result may require only N parts, because we
are multiplying two values to get it, the multiplication may
require N + 1 parts with the excess part being zero (consider
the trivial case of 1 * 1, the multiplier requires two parts to
hold the single-part result). So we add two to guarantee
enough space whilst multiplying. */
