From: paslawsk AT cadvision DOT com (Dan Paslawski) Subject: Floating Point Usage 1 May 1998 19:03:27 -0700 Message-ID: <01BD74F3.48BA8460.cygnus.gnu-win32@ts51ip86.cadvision.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 8bit To: "'gnu-win32 AT cygnus DOT com'" Cc: "'Us'" I am porting an application from Linux to Windows NT which makes intensive usage of floating point operations. I am finding slight differences in calculations between Linux (GNU Version ??) and Windows NT (using Cygwin32 B19.0), on the same machine. To be specific, floating point operations such as multiplication and division are occasionally producing differences (Linux vs WinNt) on the order of one or two bits. I would have thought the two OS's should produce identical results. My questions are, (a) does the Cygwin library make use of the Floating Point Processing capabilities? and (b) can anyone explain the differences? By the way, "uname -a" returns "CYGWIN32_NT hostname 4.0 19.0 i686 unknown" Regards Dan Paslawski Aberdeen Systems - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
