Could someone please tell me where the SGIL "Fast Math" Init is located on mac.archive.umich.edu? I have been looking, but I can't seem to find it. What is the file listed as? Thanks. Hmmm, no sig.?

I've answered this question around 10 times today... The path to the SGIL init is (drum roll please) .../archive/mac/system.extensions/init/ffpacc.sit.hqx I know, you're saying "Isn't it obvious?" now, right? I think "ffpacc" stands for "fast floating point accelerator". If you start using this and find some definite speed-ups, please post your experiences. My suspicion is that it will work well with some applications and will crash others! Since it was written in '88, I'm very curious to know why I've never heard it mentioned before, if it's as great as it seems. Perhaps an entire past civilization used it, found its problems and it just faded away. Or maybe not. -- ==== Scott Barvian ============ Department of Electrical/Computer Eng. === ==== barvian@ece.cmu.edu ====== Carnegie Mellon Univ., Pittsburgh, PA ===

For example, I was doing my finances in Microsoft Excel, and noticed some roundoff errors, and also it didn't get some dates correct (when I type in a date in a Date formatted cell, it comes out wrong.) =============================================================================== Donald Burr, Univ. of California,Berkeley | America Online: DonaldBurr INTERNET: dburr@ocf.Berkeley.EDU |_Compu$erve:_72540,3071_____________ or: 72540.3071@compuserve.COM | "Send flames to /dev/null."

Stay away from the SGIL init, it causes more problems than it fixes... Wingz absolutely hates it. It does fast math, but it gives the wrong answers +------------------------------------------------------------------------------+ |Steve Fuller | Iowa | I will choose the path that's clear. + | | State | I will choose freewill. + |xdpq8@ccvax.iastate.edu | University | -- RUSH -- + +------------------------------------------------------------------------------+
