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

</pre></div>
<p><strong>Description</strong><br>
The <code>nearbyint</code> functions round their argument to an integer value in
floating-point format, using the current rounding direction and
(supposedly) without raising the &quot;inexact&quot; floating-point exception.
See the <code>rint</code> functions for the same function with the &quot;inexact&quot;
floating-point exception being raised when appropriate.
</p>
<br>
<p><strong>Bugs</strong><br>
Newlib does not support the floating-point exception model, so that
the floating-point exception control is not present and thereby what may
be seen will be compiler and hardware dependent in this regard.
The Newlib <code>nearbyint</code> functions are identical to the <code>rint</code>
functions with respect to the floating-point exception behavior, and
will cause the &quot;inexact&quot; exception to be raised for most targets.
</p>
<br>
<p><strong>Returns</strong><br>
<var>x</var> rounded to an integral value, using the current rounding direction.
</p>
<br>
<p><strong>Portability</strong><br>
