NAME


       div,  ldiv, lldiv, imaxdiv - compute quotient and remainder of an inte-
       ger division

 

SYNOPSIS


       #include 

       div_t div(int numerator, int denominator);
       ldiv_t ldiv(long numerator, long denominator);
       lldiv_t lldiv(long long numerator, long long denominator);

       #include 

       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  quo-
       tient  is  rounded  towards  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


       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.
