| 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. |
