div(3)                                                Library Functions Manual                                               div(3)

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

LIBRARY
       Standard C library (libc, -lc)

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.

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

EXAMPLES
       After

           div_t q = div(-5, 3);

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