DIV(3)							     Linux Programmer's Manual							    DIV(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():
	   _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.
