<p><strong>Description</strong><br>
|
|
These functions compute the complex base-<var>e</var> exponential of <var>z</var>.
|
|
</p>
|
|
<p><code>cexpf</code> is identical to <code>cexp</code>, except that it performs
|
|
its calculations on <code>floats complex</code>.
|
|
</p>
|
|
<br>
|
|
<p><strong>Returns</strong><br>
|
|
The cexp functions return the complex base-<var>e</var> exponential value.
|
|
</p>
|
|
<br>
|
|
<p><strong>Portability</strong><br>
|
|
<code>cexp</code> and <code>cexpf</code> are ISO C99
|
|
</p>
