Then your result depends on the order of your input, which is usually
not a good thing.
Why would you need to determine the *number* of bins in advance? You
just need to determine where they start and stop. If for example your
epsilon is 0.5, you could determine the bins to be at [-0.5, 0.5);
[0.5, 1.5); [1.5, 2.5); ad infinitum. Then for each actual value you
encounter, you could calculate the appropriate bin, creating it first
if it doesn't already exist.
