| michael@0 | 10 | Description: return an approximation to the arc tangent of the |
| michael@0 | 11 | argument. the result is expressed in radians and |
| michael@0 | 12 | range is from -PI/2 to +PI/2. special cases: |
| michael@0 | 13 | - if x is NaN, the result is NaN |
| michael@0 | 14 | - if x == +0, the result is +0 |
| michael@0 | 15 | - if x == -0, the result is -0 |
| michael@0 | 16 | - if x == +Infinity, the result is approximately +PI/2 |
| michael@0 | 17 | - if x == -Infinity, the result is approximately -PI/2 |
