- *
- * Method :
- *      If (assume round-to-nearest) z=x*x+y*y
- *      has error less than sqrt(2)/2 ulp, then
- *      sqrt(z) has error less than 1 ulp (exercise).
- *
- *      So, compute sqrt(x*x+y*y) with some care as
- *      follows to get the error below 1 ulp:
- *
- *      Assume x>y>0;
- *      (if possible, set rounding to round-to-nearest)
- *      1. if x > 2y  use
- *              x1*x1+(y*y+(x2*(x+x1))) for x*x+y*y
- *      where x1 = x with lower 32 bits cleared, x2 = x-x1; else
- *      2. if x <= 2y use
- *              t1*y1+((x-y)*(x-y)+(t1*y2+t2*y))
- *      where t1 = 2x with lower 32 bits cleared, t2 = 2x-t1,
- *      y1= y with lower 32 bits chopped, y2 = y-y1.
- *
- *      NOTE: scaling may be necessary if some argument is too
- *            large or too tiny
- *
- * Special cases:
- *      hypot(x,y) is INF if x or y is +INF or -INF; else
- *      hypot(x,y) is NAN if x or y is NAN.
- *
- * Accuracy:
- *      hypot(x,y) returns sqrt(x^2+y^2) with error less
- *      than 1 ulps (units in the last place)
