Format
#include <stdlib.h>
div_t div(int numerator, int denominator);Language Level: ANSI
Threadsafe: Yes. However, only the function version is threadsafe. The macro version is NOT threadsafe.
Description
The div() function calculates the quotient and remainder of the division of numerator by denominator.
Return Value
The div() function returns a structure of type div_t, containing both the quotient int quot and the remainder int rem. If the return value cannot be represented, its value is undefined. If denominator is 0, an exception will be raised.
Example that uses div()
This example uses div() to calculate the quotients and remainders for a set of two dividends and two divisors.
#include <stdlib.h>
#include <stdio.h>
int main(void)
{
int num[2] = {45,-45};
int den[2] = {7,-7};
div_t ans; /* div_t is a struct type containing two ints:
'quot' stores quotient; 'rem' stores remainder */
short i,j;
printf("Results of division:\n");
for (i = 0; i < 2; i++)
for (j = 0; j < 2; j++)
{
ans = div(num[i],den[j]);
printf("Dividend: %6d Divisor: %6d", num[i], den[j]);
printf(" Quotient: %6d Remainder: %6d\n", ans.quot, ans.rem);
}
}
