Very Big numbers

Sometimes you need a quick routine, or a routine that uses encryption.
Sometimes you need a simple multiplication of Big numbers...

If so, we would like to know we developed a collection
of functions (library, dll) for working with real big numbers and all that.
(...numbers bigger than the normal data types a programmer can handle.)

It was made for Visual Basic, but can be used in
any language that can invoke a .DLL (such as C++, VBA in Excel, Access or
whatever)

It's the only DLL available for Windows for UNLIMITED BIG NUMBERS with
functions such as: +/-* Power2, Power10, MOD DIVIDE, ISPRIME, COMPARE, Xor
etc...

Calculations are sometimes even faster than you are used to,
cause everything was made in assembly.
It's shareware and it is online on http://www.big-numbers.com

To restore balance to the force, I'd ike to mention GNU MP:

http://www.gnu.org/software/gmp

which has most if not all of the features of the above DLL and is Free
Software (i.e., comes with full source code).
 
Oh, can it also be used in Visual Basic? On a Win 98 machine ?
Can it also find all 100% proven Prime Numbers?
Can it also find RSA-factors ?...
Does it include encryption modules?

Oh....

If you support Realbasic you may post on the Realbasic group, else not.

Probably, with some work, since you get the source code... but not as
easily as yours, I think.

Can yours? Amazing...

GNU MP has the Miller-Rabin probabilistic primality test and can
determine whether a number is definitely a composite, definitely a
prime, or probably a prime (with arbitrary high probability).

It also comes with an example program that demonstrates Pollard's
"rho" method for probabilistic factoring, which I don't know anything
about.

For that there is libgcrypt:

http://www.gnu.org/directory/security/libgcrypt.html


Since we are feature slinging: Does your library have optimized
assembly code for ARM, DEC Alpha 21064, 21164, and 21264, AMD 29000,
AMD K6, K6-2 and Athlon, Hitachi SuperH and SH-2, HPPA 1.0, 1.1 and
2.0, Intel Pentium, Pentium Pro/II/III, Pentium 4, generic x86, Intel
IA-64, i960, Motorola MC68000, MC68020, MC88100, and MC88110,
Motorola/IBM PowerPC 32 and 64, National NS32000, IBM POWER, MIPS
R3000, R4000, SPARCv7, SuperSPARC, generic SPARCv8, UltraSPARC, DEC
VAX, and Zilog Z8000? Does it even run on those? Does it run on
Unix, Linux, Solaris, AIX, HP UX? Does it do arbitrarily sized
floating point? Random numbers? Can I trust their quality? Can I
use it from Perl, Python, C++, Fortran, Java, Lisp, Scheme, Pascal?

And, can I get the source?

Noop. some. but somehow, it seems you're not really interested.

Sorry i mentioned the 4 year's hard work of a man who want's other people to
know
he made something he thinks is beautifull and wants to see if some else can
use it.
Sorry if i offended you in any way by mentioning that here.
I did not know that programmers should keep their programs and that it is
forbidden to

Now i know, there only a few people that are allowed to post here. Thanks.

You were allowed to post, your post was not discouraged in any way. The
reply that was sent to your first message was merely to inform others that a
GPL (freeware) version of such a library was also available and to give them
information on how to obtain more information on that. ie Giving more
options to the readers of this newsgroup, and hence further empowering them.

You replied to that message in a snarky negative way, and the thread
denegrated from there...

Can it also find all 100% proven Prime Numbers?

This wasn't really required...
There is a shareware library available (via you) which although it costs
money will have some form of available support for it, and there is also a
freeware library which doesn't cost any money however doesn't have the same
level of support one would imagine.
That's really all the discussion required on the subject. Negative comments
can be left for other newgroups.

That's simplifying it a bit, I'm afraid. Your website also sells your
library and only a crippled version is available for free. That's
mostly why I responded: advertising is frowned upon in Usenet, even
more so when it is done stealthily. So I wanted to mention GNU MP
right next to your advertisement, so that people know that there is an
alternative.

Sorry if i offended you in any way by mentioning that here. I did

No, no, you misunderstood. New to the Internet? ;-) You are allowed
to post here, but I'm also allowed to comment. Other people read what
we write and form their own opinions. Simple, eh? Now step back and
think about whether you did your business a favor by reacting in the
way you did.

Perhaps if your reply to Marius hadn't been rude, you would have gotten
a better reception.

BTW: Lots of people put lots of hard work into GMP as well (but they're
not charging for it nor advertising on Usenet)

Why is this in comp.arch.fpga?

Yes, it can:

int is_prime(BIG_NUM num)
{
for (BIG_NUM i=3 ; i<num; i++)
if (!(test_num%i) return 0;
return 1;
}

Muahaha! You didn't say anything about speed, did you :)

Honestly, if you want to sell your lib - which seems to be really a
nice piece of code - make clear what the benefits over the free
libraries are. e.g. support, small exe size, quick to implement, VB
interfaces available...

Good luck,

Thanks for all the remarks. I learned a lot in only a few hours.
Perhaps i overreacted, but mainly because in less then some minutes
after my posting, everywhere on the globe, people started commenting
on the product that we offer. No problem, but without even consulting our
site or downloading the shareware version ! (i know cause i monitored)

It's a pitty that people do not seem to take time for a good critique,
but make (mostly) negative comments on everything that's new.

Today i did some research on relevant comments and came up with this:

GMP is only free of copyright if you do not change the source of GMP with
your distributed package. Then you have to ask the consent of the makers.
You have to change and debug the code in order to make it work, so therefore
the "free" thing applies to "free time" not to the value of your time.
(source: several experienced users, not my own experience)

We support Windows as The Platform.
Our library is quick and easy to install (10 seconds) has a full, easy and
quick Help file.
We give unlimited direct forum access and we want to make this product ready
for some
big users, so we will do everything to improve our library. That means we
make real
interested users very happy, cause we make special functions, do testing
etc. for them.
For some this is not interesting, cause they are happy with what they have
got, no problem.
We provide a richness of samples, but these are currently under review and
not on-line.

Currently we are working on a special C/C++ library for Windows.
Release is scheduled. Current we support and share the Visual Basic version
and we
hope we will get some media attention around that time too, cause we think
we
developed the only full package for Visual Basic Library for Windows for Big
Numbers.

And what was the orginal reason for posting to a group that has mostly
Macintosh users? RealBasic is primarily a Macintosh product. It can be
run cross-platform to develop applications on the PC, Linux, and Mac.
It has no relationship to Visual Basic nor can run it's code or
libraries, from what I understand. I personally don't go near "The
Platform" without wearing latex.

Additionally, RealBasic has shareware and freeware code libraries of
it's own that provide similar features like a

http://homepage.mac.com/delaneyrm/
http://www.einhugur.com/
http://k.webring.com/hub?ring=xbasic

Kudos on your work on "the Platform", but you really walked into the
wrong place to tout your accomplishments. I know developers like to
show off what they've done, like breeders like to show pictures of their
kids. And good for you for owning up to your faux pas rather than get
all defensive. Good luck with your future endevours.

I've had a quick look at your site, but like most people in the various
unrelated newsgroups you posted to, I am mainly replying to your posted
comments rather than your site or your software - I am not really in a
position to judge the software itself fairly.

Today i did some research on relevant comments and came up with this:

GMP is only free of copyright if you do not change the source of GMP with
your distributed package. Then you have to ask the consent of the makers.
You have to change and debug the code in order to make it work, so
therefore
the "free" thing applies to "free time" not to the value of your time.

Source: The Microsoft FUD machine, or perhaps SCO.

Back here in the real world, GMP is LGPL'ed. That means it is *never* free
of copyright, you *never* have to ask the consent of the makers to make use
of the software as stipulated in the license (which basically says that any
software, under any license, can make use of the GMP library as desired -
however, if you make any changes to the GMP library itself, and release
those changes to others in binary form, then you also have to release the
source for the changes under the LGPL. Fair enough.), you *don't* need to
change or debug the code (unless you find that there actually is a bug in
it - in which case you have the power to change it yourself since you have
the source code).

Now, I'm not going to argue that using the GMP would cost more or less than
your library, because you are correct in saying that starting to use it is
going to take some time, and for the non-hobbyist, that time is not free.
Which is cheaper will depend on the price of your software, the ease of use
of the two libraries, suitability for their purpose, experiance of the user,
etc. The term "Free Software" has never been about price (although that's
often a nice bonus) - it is about freedom.

There are plenty of areas where FOSS is the most appropriate, and plenty
where closed source is the most appropriate. But if you are going to argue
the case for your software, then learn what you are arguing against rather
than blindly quoting "things you heard" that are obviously wrong.

arithmetic, Windows is not "The Platform". It barely ranks as "a platform".

This is where you can score big time. You will not beat the GMP on speed,
features, functionality, or flexibility - claiming you can just makes you
look silly. But you *can* beat it on ease of installation, and ease of use,
especially for smaller users who want something they can get into quickly
without reading large piles of documentation.

If I were you, I'd get the C/C++ library out fast. I don't think you are
going to reach a big audience with VB support (correct me if I'm wrong -
presumably you know your potential customer base). I think that most people
interested in this sort of functionality will be either using large
mathematical or scientific packages, or using languages like C/C++ (for
speed) or Python (for HLL programming, and speed in some types of
application). As evidence for the lack of interest in VB programming with
multiple precision arithmetic, I cite the lack of an easy-to-find website
with a downloadable VB interface to GMP - it would not be hard to do (since
the GMP can be compiled as a DLL), but still no one has bothered doing it.


I wish you luck in your business, and I hope you can make something of it.
But it pays to think carefully about what you write in technical
newsgroups - as an advertiser, you begin any thread with a big disadvantage
and must be ready for condemnation - especially when you cross-post to
irrelevant newsgroups. Being rude, sarcastic, and writing plainly incorrect
and biased arguments is not going to win you friends or customers. But
don't take it too hard (and don't take it personally!) - I doubt that many
of the people replying in this thread would have bought your library anyway.
