Working with huge Floating Point Numbers
-
Hello, I need a class which I can work with a huge floating point numbers and make an operations with them like *-/+ for example: 122354554654549878987.003253265465454597 * 65465465456654564.3212154654 I need something like this http://www.codeproject.com/cpp/largenumber.asp[^] but with floating point numbers. Is there any class like I want?

a little Googling turns up a few high-precision floating point libs for C++.

do you think http://savannah.nongnu.org/projects/hpalib[^] will fulfill my requirements I mentioned?

it says it can handle numbers in the range: 2^16384 > x > 2^[-16383] that's far greater than the numbers you gave in your post

I have problems with the files. I added the src folder to the project like that: Tools->Options->Projects And Solutions->VC++ Directories-> and to included files and source files. I'll show you here the most important code:
#include "stdafx.h" #include "num.h" #include "numDlg.h" #include "stdio.h" #include "xpre.h" BOOL CnumDlg::OnInitDialog() { CDialog::OnInitDialog(); CnumDlg::play(); return TRUE; // return TRUE unless you set the focus to a control } void CnumDlg::play() { struct xpr s; int i,n; s=xZero; do { scanf("%d",&n); s=xZero; for(i=0;i<=n;i++) s=xadd(s,xpr2(xOne,i),0); xprxpr(s,30); putchar('\n'); }while (n>0); }I earased the most of the code-just the important there. After I'm running the program I have the following Errors:1>numDlg.obj : error LNK2019: unresolved external symbol _xprxpr referenced in function "public: void __thiscall CnumDlg::play(void)" (?play@CnumDlg@@QAEXXZ) 1>numDlg.obj : error LNK2019: unresolved external symbol _xadd referenced in function "public: void __thiscall CnumDlg::play(void)" (?play@CnumDlg@@QAEXXZ) 1>numDlg.obj : error LNK2019: unresolved external symbol _xpr2 referenced in function "public: void __thiscall CnumDlg::play(void)" (?play@CnumDlg@@QAEXXZ) 1>numDlg.obj : error LNK2001: unresolved external symbol _xOne 1>numDlg.obj : error LNK2001: unresolved external symbol _xZero 1>C:\Documents and Settings\Semion Naidis\My Documents\Visual Studio 2005\Projects\num\Debug\num.exe : fatal error LNK1120: 5 unresolved externalsHow can I fix that?SnaidiS(Semion)

you'll need to either provide definitions for those functions, or remove the calls to them.

it's hard for me to say. i suggest you try to contact the authors of the class to see if they have any documentation that can help.
