NAME

       div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an integer division

SYNOPSIS

       #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)):

       lldiv():
           _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

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

       POSIX.1-2001,  POSIX.1-2008,  C89,  C99, SVr4, 4.3BSD.  The functions lldiv() and imaxdiv() were added in
       C99.

EXAMPLE

       After

           div_t q = div(-5, 3);

       the values q.quot and q.rem are -1 and -2, respectively.
