Big variable

[farshad]

Hello

for a mathematical program I need to define a variable which can store
a number with about 1,000,000 digits.

the only operation I need is the remainder of division.

I have no idea how to that. I can use any compiler you suggest.

Regards,

1,000,000??? !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!

You must create a new integer format!
This is not too hard.
An array of char with namy many bytes is my suggestion
the only operation I need is the remainder of division.
try an Eykleidian Division with same way as processors (you must learn basic
digital electronics!) with <<, >>, |, &, ~, ^

ITS TOOOOO SLOOOOW!!!

for floating point number problem is bigger
I have no idea how to that. I can use any compiler you suggest.
A compiler which support numbers with 1,000,000 digits?!
Only one?!!

Search the web for "arbitrary precision integer".

Regards,

int x = 100000000;
int b;

to devide:

b = x/17
cout << b << endl;
outputs: 5882352

However, '%' returns the remainder':

b = x%17
cout << b << endl;
outputs: 16

I forgot to say, if you're interested in the knowing the largest integer value
your computer can handle, output the value 'MAXINT':

#include <iostream>
#include <values> // for MAXINT

int main()
{
cout << MAXINT;
return 0;
}
