DESCRIPCIÓN¶

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.

VALOR DEVUELTO¶

The div_t (etc.) structure.

ESTÁNDARES¶

POSIX.1-2001, POSIX.1-2008, C89, C99, SVr4, 4.3BSD. The functions lldiv() and imaxdiv() were added in C99.

EJEMPLOS¶

After

```div_t q = div(-5, 3);
```

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