| <h3 class="section">2.10 <code>ccosh</code>, <code>ccoshf</code>—complex hyperbolic cosine</h3> |
| |
| <p><a name="index-ccosh-172"></a><a name="index-ccoshf-173"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <complex.h> |
| double complex ccosh(double complex <var>z</var>); |
| float complex ccoshf(float complex <var>z</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| These functions compute the complex hyperbolic cosine of <var>z</var>. |
| |
| <p><code>ccoshf</code> is identical to <code>ccosh</code>, except that it performs |
| its calculations on <code>floats complex</code>. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| These functions return the complex hyperbolic cosine value. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>ccosh</code> and <code>ccoshf</code> are ISO C99 |
