From: "jsm28 at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/113455] ROUNDING: IEEE Standard: Missing decimal rounding mode 'nearest, ties away from zero' for decimalxxx datatypes. Date: Wed, 17 Jan 2024 17:51:10 +0000 [thread overview] Message-ID: <bug-113455-4-55GV6e8Vvy@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-113455-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113455 --- Comment #1 from Joseph S. Myers <jsm28 at gcc dot gnu.org> --- The decimal rounding mode is set with fe_dec_setround. libdfp provides that function and an fenv.h wrapper with constant definitions including FE_DEC_TONEARESTFROMZERO. Providing that library is outside the scope of GCC; see https://sourceware.org/pipermail/libc-alpha/2019-September/106579.html for a discussion of considerations for any integration of such support directly in glibc (which would certainly be a lot of work). libdfp is at https://github.com/libdfp/libdfp but doesn't have that much activity.
