<p><strong>Description</strong><br>
|
||
|
|
These functions compute the complex hyperbolic tangent of <var>z</var>.
|
||
|
|
</p>
|
||
|
|
<p><code>ctanhf</code> is identical to <code>ctanh</code>, except that it performs
|
||
|
|
its calculations on <code>floats complex</code>.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
These functions return the complex hyperbolic tangent value.
|
||
|
|
</p>

||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>ctanh</code> and <code>ctanhf</code> are ISO C99
|
||
