  24     ECMA Section:       15.8.2.3 asin( x )
  25     Description:        return an approximation to the arc sine of the
  26                         argument.  the result is expressed in radians and
  27                         range is from -PI/2 to +PI/2.  special cases:
  28                         - if x is NaN,  the result is NaN
  29                         - if x > 1,     the result is NaN
  30                         - if x < -1,    the result is NaN
  31                         - if x == +0,   the result is +0
  32                         - if x == -0,   the result is -0
