Compute quotient and remainder of an integer division

#include <stdlib.h>div_t div(intnumerator, intdenominator);ldiv_t ldiv(longnumerator, longdenominator);lldiv_t lldiv(long longnumerator, long longdenominator);#include <inttypes.h>imaxdiv_t imaxdiv(intmax_tnumerator, intmax_tdenominator);

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*

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.

The *div_t* (etc.) structure.

The **div**(), **ldiv**(), **lldiv**(), and **imaxdiv**() functions are thread-safe.

SVr4, 4.3BSD, C89. C99. The functions **lldiv**() and **imaxdiv**() were added in C99.

After

div_t q = div(-5, 3);

the values *q.quot* and *q.rem* are -1 and -2, respectively.
