From: "jsm28 at gcc dot gnu dot org" <sourceware-bugzilla@sourceware.org> To: glibc-bugs@sources.redhat.com Subject: [Bug libc/3674] New: strtod trailing zero removal doesn't allow for hex floats Date: Thu, 07 Dec 2006 04:57:00 -0000 [thread overview] Message-ID: <20061207045700.3674.jsm28@gcc.gnu.org> (raw) The strtod removal of trailing 0s from the integer part with a negative exponent doesn't adjust the exponent correctly (by 4) for each 0 removed from a hex number. if (dig_no == int_no && dig_no > 0 && exponent < 0) do { while (! (base == 16 ? ISXDIGIT (expp[-1]) : ISDIGIT (expp[-1]))) --expp; if (expp[-1] != L_('0')) break; --expp; --dig_no; --int_no; ++exponent; } while (dig_no > 0 && exponent < 0); Testcase: #include <stdio.h> #include <stdlib.h> int main(void) { printf("%g\n", atof("0x10p-1")); return 0; } prints 1 but should print 8. -- Summary: strtod trailing zero removal doesn't allow for hex floats Product: glibc Version: 2.4 Status: NEW Severity: normal Priority: P2 Component: libc AssignedTo: drepper at redhat dot com ReportedBy: jsm28 at gcc dot gnu dot org CC: glibc-bugs at sources dot redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=3674 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
