NAME

12       labs, llabs - return a long integer absolute value
13

SYNOPSIS

15       #include <stdlib.h>
16
17       long labs(long i);
18       long long llabs(long long i);

DESCRIPTION

22       The labs() function shall compute the absolute value of the long  inte‐
23       ger operand i. The llabs() function shall compute the absolute value of
24       the long long integer operand i. If the result cannot  be  represented,
25       the behavior is undefined.
26

RETURN VALUE

28       The labs() function shall return the absolute value of the long integer
29       operand. The labs() function shall return the  absolute  value  of  the
30       long long integer operand.
