I'm all for accuracy, but the difference in 360 distance between your two numbers is 0.000000127 cm. 1.27 nanometers. That's about the size of a glucose molecule, I don't think this is the reason you don't hit the target
Technically you should round up to 799.898417 though, this will make the difference about the size of a carbon atom. Still I don't think you will be able to feel any difference...
And this will make zero difference in the calculation, no game has such accuracy obviously.
