8 | SYNOPSIS |
---|
9 | #include <stdlib.h> |
---|
10 | long long llabs(long long <[j]>); |
---|
11 | |
---|
12 | DESCRIPTION |
---|
13 | The <<llabs>> function computes the absolute value of the long long integer |
---|
14 | argument <[j]> (also called the magnitude of <[j]>). |
---|
15 | |
---|
16 | The similar function <<labs>> uses and returns <<long>> rather than |
---|
17 | <<long long>> values. |
---|
18 | |
---|
19 | RETURNS |
---|
20 | A nonnegative long long integer. |
---|
21 | |
---|
22 | PORTABILITY |
---|
23 | <<llabs>> is ISO 9899 (C99) compatable. |
---|
24 | |
---|
25 | No supporting OS subroutines are required. |
