title: Cutting down the nr of decimals in the training data
body: <p>I use Keras backed by Tensorflow to train my models and i have a question about the nr of decimals in the training data. 
  Is cutting down the nr of decimals in the training data affecting the output? My original data has 15 decimals and i would like to cut that down to 8 because that data is well represented with 8 decimals. What is your experience with this?</p>
