+   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
