| 16 | .B Abs
|

| 17 | returns the absolute value of its integer operand.

|

| 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.
