PROLOGThis manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAMElabs, llabs — return a long integer absolute value
SYNOPSIS#include <stdlib.h> long labs(long i); long long llabs(long long i);
DESCRIPTIONThe 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 VALUEThe 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.
ERRORSNo errors are defined. The following sections are informative.
