The hyperbolic sine of <em>value</em> is defined to be
(<em>e<sup>x</sup>&nbsp;-&nbsp;e<sup>-x</sup></em>)/2.0
where <i>e</i> is Euler's number, approximately 2.71828183.
<p>Special cases:
<ul>
<li>If the argument is NaN, then the result is NaN.</li>
<li>If the argument is infinite, then the result is an infinity
with the same sign as the argument.</li>
<li>If the argument is zero, then the result is a zero with the
same sign as the argument.</li>
</ul>
