NAME¶
div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an integer divisionSYNOPSIS¶
#include <stdlib.h>div_t div(int numerator, int denominator);ldiv_t ldiv(long numerator, long denominator);lldiv_t lldiv(long long numerator, long long denominator);#include <inttypes.h>imaxdiv_t imaxdiv(intmax_t numerator, intmax_t denominator);

or cc -std=c99
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.RETURN VALUE¶
The div_t (etc.) structure.CONFORMING TO¶
SVr4, 4.3BSD, C89. C99. The functions lldiv() and imaxdiv() were added in C99.EXAMPLE¶
Afterdiv_t q = div(-5, 3);the values q.quot and q.rem are -1 and -2, respectively.
