25 The div() function computes the value numerator/denominator and returns
26 the quotient and remainder in a structure named div_t that contains two
27 integer members (in unspecified order) named quot and rem. The quo‐
28 tient is rounded towards zero. The result satisfies quot*denomina‐
29 tor+rem = numerator.
30
31 The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing num‐
32 bers of the indicated type and returning the result in a structure of
33 the indicated name, in all cases with fields quot and rem of the same
34 type as the function arguments.

41 C99.
