|
<p>These functions 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 <b>long</b> integer (for the <i>ldiv</i>() function) or
|
|
<b>long long</b> integer (for the <i>lldiv</i>() function) 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>
