<a name="index-labs"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;stdlib.h&gt;
long labs(long <var>i</var>);

</pre></div>
<p><strong>Description</strong><br>
<code>labs</code> returns
the absolute value of <var>i</var> (also called the magnitude
of <var>i</var>).  That is, if <var>i</var> is negative, the result is the opposite
of <var>i</var>, but if <var>i</var> is nonnegative the result is <var>i</var>.
</p>
<p>The similar function <code>abs</code> uses and returns <code>int</code> rather than
<code>long</code> values.
</p>
<br>
<p><strong>Returns</strong><br>
The result is a nonnegative long integer.
</p>
<br>
<p><strong>Portability</strong><br>
<code>labs</code> is ANSI.
</p>
<p>No supporting OS subroutine calls are required.
</p>
