描述

tuple_is_nan_elemtuple_is_nan_elemTupleIsNanElemTupleIsNanElemTupleIsNanElemtuple_is_nan_elem checks each element of the input tuple TTTTtt whether it represents a NaN. If it does, 1 is returned for that element, otherwise 0.

例外：空输入元组

If the input tuple is empty, the operator returns an empty tuple.
