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
