michael@0:    Description:        return an approximation to the arc sine of the
michael@0:    argument.  the result is expressed in radians and
michael@0:    range is from -PI/2 to +PI/2.  special cases:
michael@0:    - if x is NaN,  the result is NaN
michael@0:    - if x > 1,     the result is NaN
michael@0:    - if x < -1,    the result is NaN
michael@0:    - if x == +0,   the result is +0
michael@0:    - if x == -0,   the result is -0
