"Error in FrequencyDiscretization Operator"

I think there is an error in the FrequencyDiscretization (CVS Version)
The square root is missing computing the number of bin, so in a exampleset with 100 examples 100 bins are generated instead only 10.
File /yale/src/com/rapidminer/operator/preprocessing/discretization/FrequencyDiscretization.java revision 1.1 to 1.5

Regards.
if (useSqrt) {
numberOfBins = exampleSet.size() - (int) exampleSet.getStatistics(currentAttribute, Statistics.UNKNOWN);
}
