<a name="index-cimag"></a>
<a name="index-cimagf"></a>
<a name="index-cimagl"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;complex.h&gt;
double cimag(double complex <var>z</var>);
float cimagf(float complex <var>z</var>);
long double cimagl(long double complex <var>z</var>);

</pre></div>
<p><strong>Description</strong><br>
These functions compute the imaginary part of <var>z</var>.
</p>
<p><code>cimagf</code> is identical to <code>cimag</code>, except that it performs
its calculations on <code>float complex</code>.
</p>
<p><code>cimagl</code> is identical to <code>cimag</code>, except that it performs
its calculations on <code>long double complex</code>.
</p>
<br>
<p><strong>Returns</strong><br>
The cimag* functions return the imaginary part value (as a real).
</p>
<br>
<p><strong>Portability</strong><br>
<code>cimag</code>, <code>cimagf</code> and <code>cimagl</code> are ISO C99
</p>
