| Returns the
geometric mean of the available values.
Uses a
SumOfLogs instance to compute sum of logs and returns
exp( 1/n (sum of logs) ). Therefore,
- If any of values are < 0, the result is
NaN.
- If all values are non-negative and less than
Double.POSITIVE_INFINITY, but at least one value is 0, the
result is 0.
- If both
Double.POSITIVE_INFINITY and
Double.NEGATIVE_INFINITY are among the values, the result is
NaN.
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.
