|
||
|
|
|
||
|
|
ANSI_SYNOPSIS
|
||
|
|
#include <stdlib.h>
|
||
|
|
long long llabs(long long j);
|
||
|
|
|
||
|
|
TRAD_SYNOPSIS
|
||
|
|
#include <stdlib.h>
|
||
|
|
long long llabs(<[j]>)
|
||
|
|
long long <[j]>;
|
||
|
|
|
||
|
|
DESCRIPTION
|
||
|
|
The <<llabs>> function computes the absolute value of the long long integer
|
||
|
|
argument <[j]> (also called the magnitude of <[j]>).
|
||
|
|
|
||
|
|
The similar function <<labs>> uses and returns <<long>> rather than
|
||
|
|
<<long long>> values.
|
||
|
|
|
||
|
|
RETURNS
|
||
|
|
A nonnegative long long integer.
|
||
|
|
|
||
|
|
PORTABILITY
|
||
|
|
<<llabs>> is ISO 9899 (C99) compatable.
|
||
|
|
|
||
|
|
No supporting OS subroutines are required.
