NAME
div, ldiv - compute the quotient and remainder
SYNOPSIS
#include <stdlib.h>
divt div (int numer, int denom);
ldivt ldiv (long int numer, long int denom);
DESCRIPTION
div computes the quotient and remainder of the division of the numerator
numer by the denominator denom. This function 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.
div returns a structure of type divt, comprising both the quotient and
remainder:
typedef struct divt {
int quot; /*quotient*/
int rem; /*remainder*/
} divt;
ldiv is similar to div, except that the arguments and the members of the
returned structure (which has type ldivt) all have type long int.
