I have a problem when comparing real numbers

       private static double EPS = 0.33333333333333;

       public static boolean eq (double a, double b) {
          return Math.abs (a - b) <EPS;
       }

when checking whether a given point belongs to a parabola, I simply substitutes the x and y
the function (y = x ^ 2 * a + x * b)
I can not pass the test 57

the fact that a decrease in EPS say up to 1E-10 then the program does not pass the test 13

I found a suitable number: 0.000050010002, but it is only for java (passes 62nd), for C++10 does not work, a stop on the 57th. Apparently my solution is not suitable for this task.

Set aside the alarm! Number: 1e-8. (I found on the forum)
