I am trying to build a decision tree using python and sklearn DecisionTreeClassifier.One of the data_type used for splitting the tree  is Boolean(let it be x).However the tree that is generated contains comparisons like x<=0.5 . This does not make sense.Can anybody suggest how to use boolean values in Decision trees.
