How can i deal with large numbers in C++. Example 26000 or numbers raised to the powers of any two large prime numbers.

I am unable to process or store large numbers in C++. Is there any way to achieve that?

You need a library for big integers. Google[^] is your friend.


[update]
Have a look at the following Wikipedia pages:


There you may also find links to known implementations.

Thank you.

Are there any simple ones , I found a simple library called 'InfInt' (with only one header file) but it cannot hold floating numbers. Are there any similar simple libraries ?

Well a big integer library is not expected to deal with floating point numbers, is it?

Is there any library you know which can store large floating numbers ? How can store values that are too small in C++ ? Does double support large values?
perhaps System.Numerics.BigInteger is what you are looking for:

System.Numerics.BigInteger is only for .NET, he doesn't say that he's using .NET, just C++ so this probably won't work for him.

How to use it in visual C++ ?
