On my VS 2012 C# compiler on test
1000 1000 1000
my program's output is
0.0000143861 288.6751345948
which doesn't seem to fit into precision (from the solution correctness criteria). But AC on timus under VS 2010 C# compiler.

Just interesting: there is no such test, timus VS 2010 is better than my VS 2012, or checker checks not equality of both numbers in output and answer, but some more weird thing?

There was incorrect checker, it checked with precision 10^-4.
It fixed now, all solutions were rejudged, 7 authors lost their AC.
