Sebastian Schelter resolved MAHOUT-1081.
----------------------------------------
Resolution: Invalid
There is no loss of precision. You are only talking about the output of
printing the cluster centers. You should read the sequence files holding the
results of the clustering.
> Precision of float to 3 digits after decimal - loss of information
