| 9 ECMA Section: 15.8.2.2 acos( x ) | |
| 10 Description: return an approximation to the arc cosine of the | |
| 11 argument. the result is expressed in radians and | |
| 12 range is from +0 to +PI. special cases: | |
| 13 - if x is NaN, return NaN | |
| 14 - if x > 1, the result is NaN | |
| 15 - if x < -1, the result is NaN | |
| 16 - if x == 1, the result is +0 | |
