1. Your recent optimizations seem to have given an overall 3% time saving in my timing tests. That's pretty good in my opinion. 2. In my accuracy tests for casin(h), I have never seen the double or long double have an error greater than 4 ULP. But for the float case I have seen 4.15 ULP. 3. I saw that you have ideas on making catanh have an error less than 1 ULP. Just saying that I saw those comments, although I didn't read them very carefully.
