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
