3.TH ABS 3 "May 15, 1985"
4.AT 3
5.SH NAME
6abs \- integer absolute value
7.SH SYNOPSIS
8.nf
9.ft B
10#include <stdlib.h>
11
12int abs(int \fIi\fP)
13.ft R
14.fi
15.SH DESCRIPTION
16.B Abs
17returns the absolute value of its integer operand.
18.SH SEE ALSO
19.BR floor (3).
20.SH BUGS
21Applying the \fIabs\fP function to the most negative integer generates a
22result which is the most negative integer. That is, abs(0x80000000)
23returns 0x80000000 as a result on a machine with 32-bit ints. Using the
24result in unsigned computations is sound however.
