I have developed the classes, to handle very large numbers in programming languages. It is virtually unlimited in number of digits (limited to memory allocation to text data) and it is able to perform following operations:
4- basic mathermatical operations: addition, subtraction, multiplication and division are available. more functions to release.
Install the class:
pip install git+http://github.com/ali/BigNumer.git
then call the class in your code:
import bignumber
