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():
           _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
           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.  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.
