<h3 class="section">2.15 <code>conj</code>, <code>conjf</code>&mdash;complex conjugate</h3>
<a name="index-conj"></a>
<a name="index-conjf"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;complex.h&gt;
double complex conj(double complex <var>z</var>);
float complex conjf(float complex <var>z</var>);

</pre></div>
<p><strong>Description</strong><br>
These functions compute the complex conjugate of <var>z</var>, 
by reversing the sign of its imaginary part.
</p>
<p><code>conjf</code> is identical to <code>conj</code>, except that it performs
its calculations on <code>floats complex</code>.
</p>
<br>
<p><strong>Returns</strong><br>
The conj functions return the complex conjugate value.
</p>
<br>
<p><strong>Portability</strong><br>
<code>conj</code> and <code>conjf</code> are ISO C99
</p>
<br>
