描述

tuple_cumultuple_cumulTupleCumulTupleCumulTupleCumultuple_cumul returns the different cumulative sums of the corresponding elements of the input tuple TupleTupleTupleTupletupletuple, i.e. the i-th element of the result tuple CumulCumulCumulCumulcumulcumul is the sum of the first i elements of the input tuple TupleTupleTupleTupletupletuple. For example, if TupleTupleTupleTupletupletuple contains the values [1,2,3,4], the output tuple CumulCumulCumulCumulcumulcumul will contain the values [1,3,6,10]. All elements of TupleTupleTupleTupletupletuple must be numbers (integer or floating point numbers). Each element of the result tuple CumulCumulCumulCumulcumulcumul will contain a floating point number if at least one element of the calculation is a floating point number. If all elements of the calculation are integer numbers the resulting sum in CumulCumulCumulCumulcumulcumul will also be an integer number.

例外：空输入元组

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