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 );
       div_t div (
	   int numerator ,
	   int denominator);
       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 value 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 value of type ldiv_t, comprising both the quotient and the remainder.

NOTES
       The abs(), labs(), div(), and ldiv() functions are supported for multithreaded 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 value of type div_t and the ldiv() function returns a value of type ldiv_t.
