      <p>Shift the bits of this integer to the left by <code>shiftAmount</code>.</p>
<p>Shifting to the left makes the number larger, effectively multiplying
the number by <code>pow(2, shiftIndex)</code>.</p>
<p>There is no limit on the size of the result. It may be relevant to
limit intermediate values by using the "and" operator with a suitable
mask.</p>
<p>It is an error if <code>shiftAmount</code> is negative.</p>
