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