| |
| <p><a name="index-llabs-35"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <stdlib.h> |
| long long llabs(long long j); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| The <code>llabs</code> function computes the absolute value of the long long integer |
| argument <var>j</var> (also called the magnitude of <var>j</var>). |
| |
| <p>The similar function <code>labs</code> uses and returns <code>long</code> rather than |
| <code>long long</code> values. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| A nonnegative long long integer. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>llabs</code> is ISO 9899 (C99) compatable. |
| |
| <p>No supporting OS subroutines are required. |
