Reference

<cstdlib> (stdlib.h)

function
<cstdlib>

lldiv

lldiv_t lldiv (long long int numer, long long int denom);
Integral division
Returns the integral quotient and remainder of the division of numer by denom ( numer/denom ) as a structure of type lldiv_t, which has two members: quot and rem.

Parameters

numer
Numerator.
denom
Denominator.

Return Value

The result is returned by value in a lldiv_t structure, which has two members (in either order):
1
2
 
long long int quot;   // quotient
long long int rem;    // remainder

/* lldiv example */
#include <stdio.h>      /* printf */
#include <stdlib.h>     /* lldiv, lldiv_t */

int main ()
{
  lldiv_t res;
  res = lldiv (31558149LL,3600LL);
  printf ("Earth orbit: %lld hours and %lld seconds.\n", res.quot, res.rem);
  return 0;
}

Output:

Earth orbit: 8766 hours and 549 seconds.


Data races

Concurrently calling this function is safe, causing no data races.

Exceptions (C++)

If either part of the result cannot be represented, it causes undefined behavior.
