Manual Section... (3) - page: div
NAMEdiv, ldiv, lldiv, imaxdiv - compute quotient and remainder of an integer division
#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);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
DESCRIPTIONThe 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 towards 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 VALUEThe div_t (etc.) structure.
CONFORMING TOSVr4, 4.3BSD, C89. The functions lldiv() and imaxdiv() were added in C99.
div_t q = div(-5, 3);the values q.quot and q.rem are -1 and -2, respectively.
