This returns the probability of the occurrence of an integer according to the Poisson distribution
where is the average or expectation value of .
Note that the argument may also be a real number. In this case what is returned is
The value is not quite a probability density: it would need to be normalized by
in order for this to be true. However it does have the property that, if , .
