CS 222 01programming Assignment 04 Chapter Points use The Fracti

Modify the Constructor for the Fraction class so that GCD is used to reduce fractions immediately. This means that the __add__ function no longer needs to reduce. Implement the remaining simple arithmetic operators (__sub__, __mul__, and __truediv__). Implement the remaining relational operators (__gt__, __ge__, __lt__, __le__, and __ne__). Modify the constructor for the Fraction class so that it checks to make sure that the numerator and denominator are both integers. If either is not an integer the constructor should raise an exception. You must use the Fraction class created in class and located on the Instructor drive as shown above. If you do not do this, you will receive a grade of 0. Add the following comments to the beginning of the program.

The task involves enhancing a Python class representing fractions, focusing on proper initialization, arithmetic operations, and comparisons. This comprehensive revision ensures that the Fraction class adheres to good programming practices, maintains mathematical accuracy, and includes proper validation mechanisms.

To begin, the constructor (__init__ method) of the Fraction class should be modified to reduce every fraction to its simplest form immediately upon creation. This is achieved by calculating the Greatest Common Divisor (GCD) of the numerator and denominator and dividing both by the GCD. Such reduction simplifies subsequent operations, as the __add__ method no longer needs to perform reduction, streamlining overall performance.

Next, the implementation of fundamental arithmetic operators—subtraction (__sub__), multiplication (__mul__), and true division (__truediv__)—are critical to make the Fraction class fully functional. These methods involve straightforward arithmetic calculations following the rules for fractions, such as cross-multiplication for subtraction and division, and numerator-times numerator for multiplication. Ensuring proper class design, these operators should return new Fraction instances representing the result of the operation.

Additionally, relational operators such as greater-than (__gt__), greater-than-or-equal (__ge__), less-than (__lt__), less-than-or-equal (__le__), and not-equal (__ne__) must be implemented. These operators compare two Fraction instances by cross-multiplied comparison of their numerators and denominators, allowing for accurate relational assessments regardless of their forms.

A critical validation improvement involves modifying the constructor to verify that both numerator and denominator are integers. If either is not, the constructor should raise a relevant exception, such as ValueError, preventing the creation of invalid Fraction instances and enhancing robustness of the class.

Throughout, it is essential to incorporate comments at the beginning of the program to specify authorship, class information, assignment number, and a brief description of the program’s purpose. This practice promotes good documentation standards and clarity for future reference or grading.

In summary, by implementing these modifications—initial reduction of fractions, complete arithmetic and relational operators, and type validation—the Fraction class becomes more efficient, reliable, and user-friendly. Such an approach not only satisfies the assignment requirements but also aligns with best programming practices in object-oriented design.
