| michael@0 | 10 | Description: return an approximation to the arc cosine of the |
| michael@0 | 11 | argument. the result is expressed in radians and |
| michael@0 | 12 | range is from +0 to +PI. special cases: |
| michael@0 | 13 | - if x is NaN, return NaN |
| michael@0 | 14 | - if x > 1, the result is NaN |
| michael@0 | 15 | - if x < -1, the result is NaN |
| michael@0 | 16 | - if x == 1, the result is +0 |
