| File Name: 15.8.2.2.js |
| ECMA Section: 15.8.2.2 acos( x ) |
| Description: return an approximation to the arc cosine of the |
| argument. the result is expressed in radians and |
| range is from +0 to +PI. special cases: |
| - if x is NaN, return NaN |
| - if x > 1, the result is NaN |
| - if x < -1, the result is NaN |
| - if x == 1, the result is +0 |
