I passed the test case above, but still WA, any suggestions? I tried adding various values of EPS to the answer, but it didn't help... Is there some special extra super duper test case?

Getting WA too.
Maybe the judge IO might be broken. I had same problem with 10750,10752.
Could someone who got AC with the old server see if it still could get AC ?

I got ac on P10751 when I print 4 digits after the decimal point.
I met precision problem several times in the new version.

btw,my 10750 code got ac in the old system.

do you get the correct formula?
if your code passed jan's data,you should get AC.
the formula is quite simple and trivial.
if you need,I can send you my ac code by pm or email.

Leonid,have you got my code?
btw,my two version for P10751,n^2 and nlogn both got wa.
I think there must be something wrong in the special judge for this problem and P216
