* ANSI_SYNOPSIS

* TRAD_SYNOPSIS
|

sl@0
|
23 |
* #include <stdlib.h>

* int abs(<[i]>)

|
30 |
* the absolute value of <[i]> (also called the magnitude
|
|
sl@0
|
31 |
* of <[i]>). That is, if <[i]> is negative, the result is the opposite
|
|
sl@0
|
32 |
* of <[i]>, but if <[i]> is nonnegative the result is <[i]>.
|
|
sl@0
|
33 |
* The similar function <<labs>> uses and returns <<long>> rather than <<int>> values.
|
|
sl@0
|
34 |
* RETURNS
|
|
sl@0
|
35 |
* The result is a nonnegative integer.
|
|
sl@0
|
36 |
* PORTABILITY
|
|
sl@0
|
37 |
* <<abs>> is ANSI.
|
|
sl@0
|
38 |
* No supporting OS subroutines are required.
