| FUNCTION |
| <<llabs>>---compute the absolute value of an long long integer. |
| |
| INDEX |
| llabs |
| |
| 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. |
