Hi!

When I enter the following command in Mathematica 8:

ConvexHull[{{65026/65027, 255/65027}, {65279/65280, 1/256}, {65281/65282, 128/32641}, {65535/65536, 1/256}}]

I get

{1, 2, 3, 4}

which is wrong, as

ListLinePlot[{{65026/65027, 255/65027}, {65279/65280, 1/256}, {65281/65282, 128/32641}, {65535/65536, 1/256}}]

proofs. Does anyone happen to know what the problem is? Is ConvexHull using numerical methods and could it be that my points are too close to each other?

Thanks in advance for any help!
