I want floating point as i have a hardware floating point unit. Since
the base version of libcook is floating point based(is from FFMpeg), I
took that. I want to get rid off all the table calculations, as most
of the tables are calculated as part of initialization, so calculating
this before hand is required as I don't have any math library function
(cos,sin,sinf,sqrt).

Can you help let me know if now my question make sense?
Please help, I will greatly appreciate your response.

Regards,
Vikas
