LlListStatistics

Returns a float that is the result of performing statistical aggregate function operation on src.

If a list entry type is not a float or an integer it is silently ignored.

Given that this operation ignores any non-numbers in a list, it can be used to tell you, in a mixed list, how many of the elements in a list are numbers (when used with the LIST_STAT_NUM_COUNT parameter.)
