DESCRIPTION
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 quotient is rounded
toward zero. The result satisfies quot*denominator+rem = numerator.
The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing
numbers 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.
