21 The div() function shall compute the quotient and remainder of the
22 division of the numerator numer by the denominator denom. If the divi‐
23 sion is inexact, the resulting quotient is the integer of lesser magni‐
24 tude that is the nearest to the algebraic quotient. If the result can‐
25 not be represented, the behavior is undefined; otherwise, quot* denom+
26 rem shall equal numer.
27
29 The div() function shall return a structure of type div_t, comprising
30 both the quotient and the remainder. The structure includes the follow‐
31 ing members, in any order:
32
33
34 int quot; /* quotient */
35 int rem; /* remainder */
