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