Kullback gives the following example (Table 2.1, Example 2.1). Let  and  be the distributions shown in the table and figure.  is the distribution on the left side of the figure, a binomial distribution with  and .  is the distribution on the right side of the figure, a discrete uniform distribution with the three possible outcomes  , ,  (i.e. ), each with probability .
Relative entropies  and  are calculated as follows. This example uses the natural log with base E (mathematical constant)|, designated  to get results in nats (see units of information):
