Thank you for your valuable feedback. I have written project proposal for
the first time in my life. So, I did not know what details to include. I
have made some changes to my proposal as per your suggestions.

I have written FFT algorithm as an optional algorithm now and made some
changes to schedule. Please let me know if it is fine now.

I was studying the code for cpp_bin_float and I have some doubts in my mind.
1. What are eval_ops_signed_type, eval_ops_unsigned_type and
2. What is the use of following lines?
typedef mpl::list<eval_ops_signed_type> signed_types;
typedef mpl::list<eval_ops_unsigned_type> unsigned_types;
typedef mpl::list<eval_ops_float_type> float_types;
These are not used in the class elsewhere. Similar lines are present in
cpp_dec_float.hpp also and not used elsewhere in the class.
3. In the function from_float_type, I think the variable number_of_digits
should be initialized to zero before using it in while loop.
Lastly, I have seen on mailing list, that some of the students are
submitting code samples. As I am busy with my end-semester exams and R&D
project, I am not able to send any sample code. As soon as I get free, I
will send it.
Thanks and regards,
