Talking bigger than long int. I am doing some math processing and would like either some example code or a library. Together with a int (or some other data type for the exponent) it will also give me a very high precision floating point data type. ----- Original Message ----- From: "Scott Simontis SIMONTIS" <age...@co...> To: <ci...@ya...> Sent: Tuesday, August 05, 2003 1:46 PM Subject: Re: [Dev-C++] How do I store HUGE numbers. > long int is my way. > > ~~Scott Simontis~~ > Programmer > > ----- Original Message ----- > From: David McKen <ci...@ya...> > Date: Tuesday, August 5, 2003 1:06 pm > Subject: [Dev-C++] How do I store HUGE numbers. > > > OK boy and girls. > > > > Other than allocating a block of memory and interpreting > > each of the bits myself how can I store really big numbers > > (Let's stick with integers for now) in memory. > > > > Signed > > David Mcken > > > > P.S.

Dear David, > Other than allocating a block of memory and interpreting > each of the bits myself how can I store really big numbers > (Let's stick with integers for now) in memory. I've got a heavy STLised library available at: http://www.programmersheaven.com/search/download.asp?FileID=26357 I describe it hifty, as it uses a pure vector as the storage. I have written a better version that uses a boost::shared_ptr to the vector as the storage. But, unfortunately, it is not downloadable. If you think you will need a copy of it, or want to test it, send me an email to send the file to you directly. I'm waiting to catch a time to implement a better version, but I always lack it! Anyway, it is likely that I start and finish this process in the few following days. If you are not in a hurry, and want the library to be more reliable, it could be better to wait.

Cool, It looks like it is exactly what I want. I would apeciate it if you would tell me when you complete it.

Have you looked at the GNU MP library (GMP). http://www.swox.com/gmp/ It has good documentation, a large number of functions, and is well tested. /Per W On Sat, 16 Aug 2003, David McKen wrote: > Cool, > It looks like it is exactly what I want. > > I would apeciate it if you would tell me when you complete > it. > > Thanks in Advance > David McKen > > ----- Original Message ----- > From: "Hossein Haeri" <ult...@em...> > To: <dev...@li...> > Sent: Saturday, August 16, 2003 12:09 PM > Subject: Re: [Dev-C++] How do I store HUGE numbers. > > > > Dear David, > > > > > Other than allocating a block of memory and > interpreting > > > each of the bits myself how can I store really big > numbers > > > (Let's stick with integers for now) in memory. > > > > I've got a heavy STLised library available at: > > > > > http://www.programmersheaven.com/search/download.asp?FileID=26357 > > > > I describe it hifty, as it uses a pure vector as the > storage. > > > > I have written a better version that uses a > boost::shared_ptr to > > the vector as the storage.

Dear David, > Cool, > It looks like it is exactly what I want. Thanks. > I would apeciate it if you would tell me when you complete > it. Well, I don't really know. But, I hope to finish it whithin the few next weaks (if no disaster jumps in). Do you want to test the version using boost::shared_ptr<>, meanwhile? > Thanks in Advance You'r welcome freind, no need to thanks!

Dear Per, > Have you looked at the GNU MP library (GMP). > http://www.swox.com/gmp/ Thank you for informing me about a new link. > It has good documentation, a large number of functions, and is well > tested. Oh yeah! It seems so (and I'm sure that's actually the case). But, maybe it is not that bad to let my library to be tested. Anyway, if David needs a reliably tested library, there is another one that is so reliable in comparison with mine. I don't have a direct link to it, but it is (likely to be) named BigInt (or some variation of it) , and it is somewhere whithin the boost huge repository. It is best to search for it in: http://www.boost.org Regards, --Hossein -- __________________________________________________________ Sign-up for your own personalized E-mail at Mail.com http://www.mail.com/?sr=signup CareerBuilder.com has over 400,000 jobs.

GMP isn't just big integers - it also contains code for big real numbers. /Per W On Sun, 17 Aug 2003, Hossein Haeri wrote: > Dear Per, > > > Have you looked at the GNU MP library (GMP). > > http://www.swox.com/gmp/ > > Thank you for informing me about a new link. > > > It has good documentation, a large number of functions, and is well > > tested. > > Oh yeah!
