wtf?? My equal solutions on Pascal and C++ has WA on tests 3 and 2. Why? I used some formulas - sqrt(2)/2, cos(pi/4), and others.

May be, error in real types (I used some variants:
Pascal - extended
C++ - double, long double
)

I read other topics about this problem, but I have not AC :)

Thanks.

I used:
const double root = sqrt(2.0)/2.0;

Ups.. double post..
