Computes the quotient and the remainder of two integer values of any size as a single operation.


imaxdiv_t imaxdiv(
   intmax_t numer,
   intmax_t denom


The numerator.

The denominator.

Return Value

imaxdiv called with arguments of type intmax_t returns a structure of type imaxdiv_t that comprises the quotient and the remainder.


The imaxdiv function divides numer by denom and thereby computes the quotient and the remainder. The imaxdiv_t structure contains the quotient, intmax_t quot, and the remainder, intmax_t rem. The sign of the quotient is the same as that of the mathematical quotient. Its absolute value is the largest integer that is less than the absolute value of the mathematical quotient. If the denominator is 0, the program terminates with an error message.

   x = atoll(argv[1]);
   y = atoll(argv[2]);

   printf("The call to imaxdiv(%lld, %lld)\n", x, y);

When built and then called with command line parameters of 9460730470000000 8766, the code generates this output:

The call to imaxdiv(9460730470000000, 8766)
results in a quotient of 1079252848505, and a remainder of 5170
