The div() function computes the value numerator/denominator and returns
the quotient and remainder in a structure named div_t that contains two
integer members (in unspecified order) named quot and rem. The quo-
tient is rounded toward zero. The result satisfies quot*denomina-
tor+rem = numerator.
The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing num-
bers of the indicated type and returning the result in a structure of
the indicated name, in all cases with fields quot and rem of the same
type as the function arguments.
The div_t (etc.) structure.
SVr4, 4.3BSD, C89. The functions lldiv() and imaxdiv() were added in
div_t q = div(-5, 3);
the values q.quot and q.rem are -1 and -2, respectively.
