Format
#include <stdlib.h> lldiv_t lldiv(long long int numerator, long long int denominator);
Language Level: Extension
lldiv calculates the quotient and remainder of the
division of numerator by denominator.
Return Value
lldiv returns a structure of type
lldiv_t, containing both the quotient (long long int quot) and
the remainder (long long int rem). If the value cannot be
represented, the return value is undefined. If denominator
is 0, an exception is raised.
Example
This example uses lldiv to calculate the
quotients and remainders for a set of two dividends and two
divisors.
#include <stdio.h> #include <stdlib.h>
int main(void)
{
long long int num[2] = { 45,-45 );
long long int den[2] = { 7,-7 );
lldiv_t ans; /* lldiv_t is a struct type containing two long long ints:
'quot' stores quotient; 'rem' stores remainder */
short i,j;
printf("Results of long long division:\n");
for (i = 0; i < 2; i++)
for (j = 0; j < 2; j++) {
ans = lldiv(num[i], den[j]);
printf("Dividend: %4lld Divisor: %4lld Quotient: %4lld "
"Remainder: %4lld\n", num[i], den[j], ans.quot, ans.rem);
}
return 0;
