| <h3 class="section">2.1 <code>cabs</code>, <code>cabsf</code>—complex absolute-value</h3> |
| |
| <p><a name="index-cabs-154"></a><a name="index-cabsf-155"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <complex.h> |
| double cabs(double complex <var>z</var>); |
| float cabsf(float complex <var>z</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| These functions compute compute the complex absolute value |
| (also called norm, modulus, or magnitude) of <var>z</var>. |
| |
| <p><code>cabsf</code> is identical to <code>cabs</code>, except that it performs |
| its calculations on <code>floats complex</code>. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| The cabs functions return the complex absolute value. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>cabs</code> and <code>cabsf</code> are ISO C99 |
