Double.Min_Value not working as expected

I have the following code but it doesn't go through the if when mutual information is zero. Any idea what is going wrong?

int largestEntropyIndex = Integer.MIN_VALUE;
        double largestMutualInfomation = Double.MIN_VALUE;
        for (int i = 0; i < attributes.size(); i++) {
            String attrName=this.attributes.get(i);
            double conditionalEntropy = calcConditionalEntropy(i,
                                                               instances,
                                                               this.attributeValues.get(attrName).size(),
                                                               this.labels.size());

            System.out.println("conditional entropy is: "+conditionalEntropy);
            double mutualInformation = entropy - conditionalEntropy;
            if (mutualInformation > largestMutualInfomation){
                largestMutualInfomation = mutualInformation;
                largestEntropyIndex = i;
            }
