[PATCH v4 05/12] math: Use an improved algorithm for hypotl (ldbl-128)

[Wilco Dijkstra]

Hi Adhemerval,


+  /* If ay is tiny, scale both inputs up.  */
+  if (__glibc_unlikely (ay < TINY_VAL))
+    {
+      if (__glibc_unlikely (ax >= ay / EPS))
+       return ax;

Why not return ax + ay like in the other special cases? It's more accurate for rounding
upwards, and it's best to keep the code as similar as possible as the double version.

Cheers,
Wilco
