          <p>Returns the minimum number of bits required to store this integer.</p>
<p>The number of bits excludes the sign bit, which gives the natural length
for non-negative (unsigned) values.  Negative values are complemented to
return the bit position of the first bit that differs from the sign bit.</p>
