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; 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   towards   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.
