The div() function shall compute the quotient and remainder
of the division of the numerator numer by the
denominator denom. 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, quot* denom+
rem shall equal numer.
The div() function shall return a structure of type div_t,
comprising both the quotient and the remainder. The
structure includes the following members, in any order:
int quot; /* quotient */
int rem; /* remainder */
No errors are defined.
