12 TRAD_SYNOPSIS

17 DESCRIPTION
18 The <<llabs>> function computes the absolute value of the long long integer
19 argument <[j]> (also called the magnitude of <[j]>).
20 
21 The similar function <<labs>> uses and returns <<long>> rather than
22 <<long long>> values.
23 
24 RETURNS
25 A nonnegative long long integer.
26 
27 PORTABILITY
28 <<llabs>> is ISO 9899 (C99) compatable.
29 
30 No supporting OS subroutines are required.
