- Group delay parameter d is fully adjustable. It is treated as a rational number and expressed as a fraction.

- Special care is taken to retain the accuracy throughout the computation and obtain precise results in the form of fractions.

- As the computation is performed in intgers, and in consideration of the limited integer length in this implementation, care should be exercised when the numbers involved internally approach (2^{53}-1).
