35 // To compute asin(s), separate schemes are used when s is in different
40 // asin(s)=asin(t)+asin(r), where r=s*sqrt(1-t^2)-t*sqrt(1-s^2)
41 // asin(r)-r evaluated as 7-degree polynomial (c3*r^3+c5*r^5+c7*r^7)
51 // asin(|s|)=pi/2-asin(t)+asin(r), r=s*t-sqrt(1-s^2)*sqrt(1-t^2)
52 // asin(r) evaluated as polynomial (same as above)
58 // |s| in [255/256,1): asin(|s|)=pi/2-asin(sqrt(1-s^2))
64 // asin(NaN) = quiet NaN, and raise invalid exception
65 // asin(INF) = QNaN and raise invalid exception
66 // asin(x) = QNaN and raise invalid exception, for |x|>1.0
67 // asin(+/-0) = +/-0
