| <h3 class="section">2.12 <code>cimag</code>, <code>cimagf</code>—imaginary part</h3> |
| |
| <p><a name="index-cimag-176"></a><a name="index-cimagf-177"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <complex.h> |
| double cimag(double complex <var>z</var>); |
| float cimagf(float complex <var>z</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| These functions compute the imaginary part of <var>z</var>. |
| |
| <p><code>cimagf</code> is identical to <code>cimag</code>, except that it performs |
| its calculations on <code>floats complex</code>. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| The cimag functions return the imaginary part value (as a real). |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>cimag</code> and <code>cimagf</code> are ISO C99 |
