Thx , to vrld and Inny for useful info. But it should be interesting (i hope not only for me), how you solve such problems?
Now i have one general solution round ( http://en.wikipedia.org/wiki/Rounding#R ... _from_zero ) all numbers before comparation.

Assuming there is no error in your calculations, if the point is "out" of vector2, even for a tiny fraction, then I would consider that there is simply no collision. I would act as if the vectors were 2 million units away. No messing around with rounding numbers of any kind. If you need t...

Hi i have question about lua and game development. Problem that lua round's values and when i compare this rounded values they a minimally lower or greater than they should be. E.g. I have to 2 vectors and i want find point of their crossing (if such exists). I find point of crossing between 2 lines...
