abs(3)
NAME
  abs, div, labs, ldiv - Computes absolute value and division of integers

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 );

LIBRARY
  Standard C Library (libc)

PARAMETERS
  i   For abs(), specifies some integer. For labs(), specifies some long
      integer.

  numerator
      For div(), specifies some integer. For ldiv(), specifies some long
      integer.

  denominator
      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.

  AES Support Level:
      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.
