Yes, I will. Thanks

Yes, I will summarize. For now I will be using fixed points. And later
I will write code specific to platforms which support floats and SIMD.
I hope that is okay.

Before this project I never knew there was something like fixed-point. I
knew that at the end of the day floats are also stored in bit array, but
I didn't know that something like this is used until I started working
on this project.
At first it was a bit frustrating to work with them but I have gotten
used to them now. So yeah it has been a good learning opportunity :)

One more thing, shouldn't it be a `minmum level of warnings.' ?
