41 File Name: 15.8.2.3.js
42 ECMA Section: 15.8.2.3 asin( x )
43 Description: return an approximation to the arc sine of the
44 argument. the result is expressed in radians and
45 range is from -PI/2 to +PI/2. special cases:
46 - if x is NaN, the result is NaN
47 - if x > 1, the result is NaN
48 - if x < -1, the result is NaN
49 - if x == +0, the result is +0
50 - if x == -0, the result is -0
