| <h3 class="section">2.20 <code>ldiv</code>—divide two long integers</h3> |
| |
| <p><a name="index-ldiv-34"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <stdlib.h> |
| ldiv_t ldiv(long <var>n</var>, long <var>d</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| Divide |
| <var>n</var>/<var>d</var>, |
| returning quotient and remainder as two long integers in a structure <code>ldiv_t</code>. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| The result is represented with the structure |
| |
| <pre class="smallexample"> typedef struct |
| { |
| long quot; |
| long rem; |
| } ldiv_t; |
| </pre> |
| <p>where the <code>quot</code> field represents the quotient, and <code>rem</code> the |
| remainder. For nonzero <var>d</var>, if `<var>r</var><code> = ldiv(</code><var>n</var><code>,</code><var>d</var><code>);</code>' then |
| <var>n</var> equals `<var>r</var><code>.rem + </code><var>d</var><code>*</code><var>r</var><code>.quot</code>'. |
| |
| <p>To divide <code>int</code> rather than <code>long</code> values, use the similar |
| function <code>div</code>. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>ldiv</code> is ANSI. |
| |
| <p>No supporting OS subroutines are required. |
