imaxdiv(3)


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():
       _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.

   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.
