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 || _POSIX_C_SOURCE >= 200112L;
	   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 toward zero.  The result  satisfies  quot*denomina-
       tor+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.

ATTRIBUTES

   Multithreading (see pthreads(7))
       The div(), ldiv(), lldiv(), and imaxdiv() functions are thread-safe.

CONFORMING TO

       SVr4, 4.3BSD, C89. C99.	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.

NAME

       div, ldiv, lldiv - compute the quotient and remainder

SYNOPSIS

       #include <stdlib.h>

       div_t div(int numer, int denom);

       ldiv_t ldiv(long int numer, long int denom);

       lldiv_t lldiv(long long numer, long long denom);

DESCRIPTION

       The div() function computes the quotient and remainder of the division of the numerator numer by the denominator denom. It provides a well-
       defined semantics for the signed integral division and remainder operations, unlike the implementation-defined semantics  of  the  built-in
       operations.    The  sign  of the resulting quotient is that of the algebraic quotient, and if the division is inexact, the magnitude of the
       resulting quotient is the largest integer less than the magnitude of the algebraic quotient. If the  result  cannot  be	 represented,  the
       behavior is undefined; otherwise, quotient * denom + remainder will equal numer.

       The  ldiv()  and lldiv() functions are similar to div(), except that the arguments and the members of the returned structure are different.
       The ldiv() function returns a structure of type ldiv_t and has type long int.  The lldiv() function returns a structure of type lldiv_t and
       has type long long.

RETURN VALUES

       The div() function returns a structure of type div_t, comprising both the quotient and remainder:

	 int   quot;   /*quotient*/
	 int   rem;    /*remainder*/

       The  ldiv()  function returns a structure of type ldiv_t and lldiv() returns a structure of type lldiv_t, comprising both the  quotient and
       remainder:

	 long int   quot;   /*quotient*/
	 long int   rem;    /*remainder*/
