|
|
|
|
<p>The <i>div</i>() function shall compute the quotient and remainder of the division of the numerator <i>numer</i> by the
|
|
denominator <i>denom</i>. If the division is inexact, the resulting quotient is the integer of lesser magnitude that is the nearest
|
|
to the algebraic quotient. If the result cannot be represented, the behavior is undefined; otherwise, <i>quot</i>* <i>denom</i>+
|
|
<i>rem</i> shall equal <i>numer</i>.</p>

<blockquote>
|
|
<p>The <i>div</i>() function shall return a structure of type <b>div_t</b>, comprising both the quotient and the remainder. The
|
|
structure includes the following members, in any order:</p>

|
|
|
<pre>
|
|
<tt>int quot; /* quotient */

int rem; /* remainder */
