From: "jakub at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libquadmath/94756] strtoflt128 assigns some subnormals incorrectly on MS Windows Date: Wed, 18 Jan 2023 18:40:35 +0000 [thread overview] Message-ID: <bug-94756-4-h2g2TP2GmV@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-94756-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94756 --- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I can reproduce it on x86_64-linux with -m32 too: f1: 0x0.000000014707e947d757fbf6f7p-16382 f2: 0x0.000000014707e946d257f2f674b9p-16382 but can't with -m64 nor when using glibc 2.35 strtof128 (in that case it works fine both with -m32 and -m64): #define _GNU_SOURCE #include <stdlib.h> #include <stdio.h> #include <math.h> int main () { char buffer[48]; _Float128 f1 = strtof128 ("1e-4941", NULL); _Float128 f2 = 1e-4941F128; strfromf128 (buffer, 45, "%a", f1); printf ("f1: %s\n", buffer); strfromf128 (buffer, 45, "%a", f2); printf ("f2: %s\n", buffer); return 0; }
