Returns the hyperbolic cosine of a double value. The hyperbolic cosine of x is defined to be (e<sup>x</sup> + e<sup>-x</sup>)/2 where e is Math#E Euler's number.
Special cases: <ul>
<li>If the argument is NaN, then the result is NaN.
<li>If the argument is infinite, then the result is positive infinity.
<li>If the argument is zero, then the result is 1.0.
</ul>
