.SH NAME

abs \- integer absolute value
|

.SH SYNOPSIS
|

#include <stdlib.h>
|
|
|
|
int abs(int \fIi\fP)

.SH DESCRIPTION
|
|
.B Abs
|
|
returns the absolute value of its integer operand.
|
|
.SH SEE ALSO
|
|
.BR floor (3).
|
|
.SH BUGS
|
|
Applying the \fIabs\fP function to the most negative integer generates a
|
|
result which is the most negative integer. That is, abs(0x80000000)
|
|
returns 0x80000000 as a result on a machine with 32-bit ints. Using the
|
|
result in unsigned computations is sound however.
