Big_Real is a C++ class that can hold a real number with unlimited number of digits (no minimum or maximum boundries) and supports math functions between Big_Reals.

This library needs another library to make composition of another class called "Big_Decimal_Int" which can hold an integer number with unlimited digits, we created this library before..
But to practice working with other programmers' code, we used a "Big_Decimal_Int" library that was written by another team

• Addition with other BigReal-s ( + operator )
• Subtraction with other BigReal-s ( - operator )
• Comparing with another BigReal ( < , > , = ) operators
• Assigning BigReal to another BigReal
• Using input and output streams with BigReal-s
• Initalizing the BigReal from different data types (BigDecimalInt, int, double, etc..)

• Practice Object-Oriented-Programming concepts using C++ (Encapsulation - Abstraction - Composition - etc..)
• Practice building systems using OOP modeling and design with C++
• Practice working in a team and integrating the code together to come up with a final working program
• Practice working and using another library that wasn't written you, and using its public interface efficiently to complete our project
