How can a neural net output values other than 0 or 1?

I am familiar with basic artificial neural networks and can program one myself using a genetic algorithm to train weights. But since the neurons only output a 0 or a 1, how can you use a neural network to use data that is not binary. Like if my inputs are 5, 7, 99 and i want it to output 44, 2, 3 how do I make the neural net do that? It only outputs 0 or 1 !
