Interpretation of classification result of Neural Net

Hi everybody,
I am executing a classification with TrainVectorClassifier and VectorClassifier. I have already generated the results to RandomForest and SVM. When I execute ANN method, the predicted column generates a result I can’t understand. My classes are numbered 1 to 7 and the ANN results presents a predicted column with a 10-digit number, like:

What this numbers mean? How can i relate them to final classification?

Thanks by any help.
