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
     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.
