I remember seeing this on one architecture (don't remember what it was, it was about 8-10 years ago), only for doule precision types (ai is/was double), and we got around it by converting to strings. CA is very good about the conversion, so this never turned into a problem (the application may still be running like that, I don't remember what it was and whether we still have the device) HTH, Maren On Fri, 29 Feb 2008, Rok ?abjan wrote: Hi Heinrich,Received: from epics.aps.anl.gov (zora.aps.anl.gov [164.54.10.60]) by o2.aps.anl.gov (8.13.8+Sun/8.12.9) with ESMTP id m1SMcI0A002994 for <[email protected]>; Thu, 28 Feb 2008 16:38:18 -0600 (CST) Received: from zora.aps.anl.gov (localhost [127.0.0.1]) by epics.aps.anl.gov (8.13.8+Sun/8.12.9) with ESMTP id m1SMZNDR029862; Thu, 28 Feb 2008 16:35:24 -0600 (CST) Received: from herald.aps.anl.gov (herald.aps.anl.gov [164.54.50.61]) by epics.aps.anl.gov (8.13.8+Sun/8.12.9) with ESMTP id m1SH2fot005792 for <[email protected]>; Thu, 28 Feb 2008 11:02:41 -0600 (CST) Received: from aps.anl.gov (hestia.aps.anl.gov [164.54.98.20]) by herald.aps.anl.gov (8.13.7/8.13.7) with ESMTP id m1SH1thE009602 for <[email protected]>; Thu, 28 Feb 2008 11:01:55 -0600 (CST) Received: from ([128.171.90.17]) by hestia.aps.anl.gov with ESMTP id 4440338.11519070; Thu, 28 Feb 2008 11:02:21 -0600 Date: Thu, 28 Feb 2008 07:02:20 -1000 (HST) From: Maren Purves <[email protected]> To: =?ISO-8859-15?Q?Rok_=A6abjan?= <[email protected]> Subject: Re: floating point problem in CA?
