<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;math.h&gt;
double round(double <var>x</var>);
float roundf(float <var>x</var>);

</pre></div>
<p><strong>Description</strong><br>
The <code>round</code> functions round their argument to the nearest integer
value in floating-point format, rounding halfway cases away from zero,
regardless of the current rounding direction.  (While the &quot;inexact&quot;
floating-point exception behavior is unspecified by the C standard, the
<code>round</code> functions are written so that &quot;inexact&quot; is not raised if the
result does not equal the argument, which behavior is as recommended by
IEEE 754 for its related functions.)
</p>
<br>
<p><strong>Returns</strong><br>
<var>x</var> rounded to an integral value.
