描述

tuple_subtuple_subTupleSubTupleSubTupleSubtuple_sub computes the difference of the input tuples D1D1D1D1d1d1 and D2D2D2D2d2d2. If both tuples have the same length the corresponding elements of both tuples are subtracted. Otherwise, either D1D1D1D1d1d1 or D2D2D2D2d2d2 must have length 1. In this case, the subtraction is performed for each element of the longer tuple with the single element of the other tuple. If two integer numbers are subtracted, the result is again an integer number. If one of the operands is a floating point number, the result is a floating point number. The subtraction of strings is not allowed.

例外：空输入元组

If either or both of the input tuples are empty, the operator returns an empty tuple.
