Subject: [Bug math/5781] Slow dbl-64 sin/cos/sincos for special values
Date: Fri, 24 Apr 2015 20:36:00 -0000	[thread overview]
Message-ID: <bug-5781-131-38IY1Du26N@http.sourceware.org/bugzilla/> (raw)
In-Reply-To: <bug-5781-131@http.sourceware.org/bugzilla/>

--- Comment #18 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
As I outlined in 
<https://sourceware.org/ml/libc-alpha/2013-07/msg00444.html>, and as 
described in the discussion of accuracy goals in the glibc manual, I don't 
think functions such as sin and cos should try to be correctly rounded, 
only functions such as crsin and crcos (if added).
