lldiv

DIV(3)                     Linux Programmer's Manual                    DIV(3)

NAME
       div,  ldiv, lldiv, imaxdiv - compute quotient and remainder of an inte-
       ger 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  quo-
       tient  is  rounded  toward  zero.   The result satisfies quot*denomina-
       tor+rem = numerator.

       The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing num-
       bers  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  ll-
       div() 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.
