I don't see why that would help. Of course there is more precision in terms of decimal places around 1 than around 360. But if you use 360 each 1 represents a much smaller piece of the circle. To put it another way...it's about significant digits. A float has about 7 and a double about 15. It does not matter whether you use 0 to 360 or 0 to 3.6 million...the number of digits that are meaningful remain the same.
