Question

I am solving a problem where I need to deal with 120 digit binary numbers. there is no simple data type and I have understood I need to use bigint. I am using 64 bit win 7 HB and visual studio 2010 ultimate as my ide for c++.

Can any one explain how do I create variable of bigint and how do I perform functions of square and square root on them.

Use this library..

and perform calculations as normal..

a = 12333333333333333333333333333333333;
cout << a * a;
