| 15 | .SH DESCRIPTION
|
---|
| 16 | .B Abs
|
---|
| 17 | returns the absolute value of its integer operand.
|

| 18 | .SH SEE ALSO
|
---|
| 19 | .BR floor (3).
|
---|
| 20 | .SH BUGS
|
---|
| 21 | Applying the \fIabs\fP function to the most negative integer generates a
|
---|
| 22 | result which is the most negative integer. That is, abs(0x80000000)
|
---|
| 23 | returns 0x80000000 as a result on a machine with 32-bit ints. Using the
|
---|
| 24 | result in unsigned computations is sound however.
