NAME

abs, div, labs, ldiv - Computes absolute value and division of integers  

LIBRARY

Standard C Library (libc.a)  

SYNOPSIS

#include <stdlib.h>

int abs (
    int i );

long labs (
    long i );

struct div_t div (
    int numerator ,
    int denominator);

struct ldiv_t ldiv (
    long numerator,
    long  denominator);  

PARAMETERS

For abs(), specifies some integer. For labs(), specifies some long integer. For div(), specifies some integer. For ldiv(), specifies some long integer. For div(), specifies some integer. For ldiv(), specifies some long integer.  

DESCRIPTION

The abs() function returns the absolute value of its integer operand.

The div() function computes the quotient and remainder of the division of the numerator numerator by the denominator denominator. If the division is inexact, the sign of the resulting quotient is that of the algebraic quotient, and the magnitude of the resulting quotient is the largest integer less than the magnitude of the algebraic quotient. If the result cannot be represented (for example, if the denominator is 0), the behavior is undefined. The div() function returns a structure of type div_t, comprising both the quotient and the remainder.

The labs() and ldiv() functions perform the same functions as abs() and div() respectively, but accept long integers rather than integers as parameters. The ldiv() function returns a structure of type ldiv_t, comprising both the quotient and the remainder.  

NOTES

The abs(), labs(), div(), and ldiv() functions are supported for multi-threaded applications.

A two's-complement integer can hold a negative number whose absolute value is too large for the integer to hold. When given this largest negative value, the abs() function returns the same value. Full use  

RETURN VALUES

The abs() function and labs() function return the absolute value of their arguments.

The div() function returns a structure of type div_t and the ldiv() function returns a structure of type ldiv_t.
