NAME
div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an integer division
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <stdlib.h>div_t div(int \nnumerator\n, int \ndenominator\n);\n
\nldiv_t ldiv(long \nnumerator\n, long \ndenominator\n);\n
\nlldiv_t lldiv(long long \nnumerator\n, long long \ndenominator\n);#include <inttypes.h>imaxdiv_t imaxdiv(intmax_t \nnumerator\n, intmax_t \ndenominator\n);lldiv():
\n
_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112LDESCRIPTION
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.

HISTORY
POSIX.1-2001, C89, C99, SVr4, 4.3BSD.
lldiv() and imaxdiv() were added in C99.
EXAMPLES
After
div_t q = div(-5, 3);the values q.quot and q.rem are -1 and -2, respectively.
