The result is NaN iff all values are NaN
(i.e. NaN values have no impact on the value of the statistic).
If any of the values equals Double.POSITIVE_INFINITY,
the result is Double.POSITIVE_INFINITY.
Note that this implementation is not synchronized. If
multiple threads access an instance of this class concurrently, and at least
one of the threads invokes the increment() or
clear() method, it must be synchronized externally.
