Break off double at all.
For example.
sqrt(x*x+y*y)<=R ~ (x*x+y*y)<=R*R.
On this way you can make you algo
absolutely i.e, mathematically correctly.

Эх, это не идея... Так только уберет совсем невозможные варианты. Это реализовано мной... Wa10. Я попробовал проверить приндлежность двух точек одному потенциально возможному в окружности с данным радиусом вписанному квадрату... и получил wa2. полный трындец... можно конечно понасиловать тимус, чтобы добыть тесты... но это плохой дао. так как старость может придти раньше успеха. Кто-нибудь дайте AC-алгоритм, или его математическую реализацию.... я больше не могу ничего придумать
PS. if you want translate... use RU-EN translator.

Use for example a system:
s*x1+t*y1==R/sqrt(2)
s*x2+t*y2==-R/sqrt(2)
must be:s^2+t^2==1

What does this formula stand for? I don't know what is "~" here?
Is this enough to solve the problem, or is there anything else to be considered?

Thanks
