<p>For the purpose of rounding, <code>-0.0</code> is considered to be below <code>0.0</code>,
and <code>-0.0</code> is therefore considered closer to negative numbers than <code>0.0</code>.
This means that for a value, <code>d</code> in the range <code>-0.5 &lt; d &lt; 0.0</code>,
the result is <code>-0.0</code>.</p>
