Wrap a {@link CheckedDoubleBinaryOperator} in a {@link DoubleBinaryOperator}.
<p>
Example:
<pre><code>
DoubleStream.of(1.0, 2.0, 3.0).reduce(Unchecked.doubleBinaryOperator((d1, d2) -> {
    if (d2 &lt; 0.0)
        throw new Exception("Only positive numbers allowed");

    return d1 + d2;
}));
</code></pre>
