What is the easiest way to handle huge numbers in C? I need to store values in the Area 1000^900
, or in more human readable form 10^2700
.
Does anybody know of an easy way to do that? Any help would really be appreciated!
bigint is a C++ library which can handle Very very Big Integers. It can calculate factorial of 1000000... it can go any big. It may be useful in Competitive Coding and Scientific Calculations which deals with very very large Integers. It can also be used in Decryption process.
BigInt is a new data type intended for use when integer values are larger than the range supported by the Number data type. This data type allows us to safely perform arithmetic operations on large integers, represent high-resolution timestamps, use large integer IDs, and more without the need to use a library.
The bigint data type is intended for use when integer values might exceed the range that is supported by the int data type. bigint fits between smallmoney and int in the data type precedence chart. Functions return bigint only if the parameter expression is a bigint data type.
Handling large numbers in C++? In C++, we can use large numbers by using the boost library. This C++ boost library is widely used library. This is used for different sections. It has large domain of applications.
Use libgmp:

There are a few libraries to help you do this (arbitrary precision mathematics):
Assuming this isn't work related (ie you're doing it for fun or its a hobby or just an oportunity to learn something), coding up a library for arbitrary precision maths is a relatively interesting project. But if you need to absolutely rely on it and aren't interested in the nuts and bolts just use a library.
