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
exponent squaring?

etc...

Calculations are sometimes even faster than you are used to,
cause everything was made in assembly.
For which cpu's have you been optimizing?

% and / are very slow operations at most cpu's.

64 bits?

It's shareware and it is online on http://www.big-numbers.com

The only interesting thing is whether your library is faster at x86-64 than
the GNU tools. The rest doesn't count.

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....

Just restoring balance...

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).
