labs, llabs — return a long integer absolute value

Synopsis

#include <stdlib.h>

long labs(long i);
long long llabs(long long i);

Description

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1‐2008 defers to the ISO C standard.

The labs() function shall compute the absolute value of the long integer operand i. The llabs() function shall compute the absolute value of the long long integer operand i. If the result cannot be represented, the behavior is undefined.

Return Value

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

The llabs() function shall return the absolute value of the long long integer operand.
