From: "joseph at codesourcery dot com" <sourceware-bugzilla@sourceware.org> To: glibc-bugs@sourceware.org Subject: [Bug math/28472] pow(10, i) accuracy Date: Mon, 24 Jan 2022 21:56:01 +0000 [thread overview] Message-ID: <bug-28472-131-QarGV3Wc3e@http.sourceware.org/bugzilla/> (raw) In-Reply-To: <bug-28472-131@http.sourceware.org/bugzilla/> https://sourceware.org/bugzilla/show_bug.cgi?id=28472 --- Comment #7 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- Being correctly rounded is out of scope for both pow and exp10 and failures to be correctly rounded should not be considered problems, only errors of more than a few ulps are bugs in glibc. We're a lot more likely to get cr_exp10 than cr_pow, but that would depend on both CORE-MATH implementing it and someone doing the work to integrate it into glibc (note that the present CORE-MATH implementations aren't suitably portable for glibc at present - they depend on 64-bit systems, for example, via hardcoded assumptions on the size of long and requirements in places for 128-bit integer types - are very lacking in comments, and may not meet the requirements for correct exceptions from cr_*). -- You are receiving this mail because: You are on the CC list for the bug.
