| 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 |
