abs, div, labs, ldiv - Computes absolute value and division
of integers
#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 );
Standard C Library (libc)
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.
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.
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
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.
