It converts a string into float (simply understood as internal scientific notation), and then converts that float back to a string when printed (if this is entered in a prompt). In simple words, it applies the standard exponential function to each element of the input vector and normalizes these values by dividing by the sum of all these exponentials; this normalization ensures that the sum of the components of the output vector is 1. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. With Python, it is possible to use the ** operator to calculate powers.
