tuple_cumultuple_cumulTupleCumulTupleCumul (Operator)

Name

tuple_cumultuple_cumulTupleCumulTupleCumul — Calculate the cumulative sums of a tuple.

tuple_cumultuple_cumulTupleCumulTupleCumulTupleCumul returns the different cumulative sums of the corresponding elements of the input tuple TupleTupleTupleTupletuple, i.e. the i-th element of the result tuple CumulCumulCumulCumulcumul is the sum of the first i elements of the input tuple TupleTupleTupleTupletuple. For example, if TupleTupleTupleTupletuple contains the values [1,2,3,4], the output tuple CumulCumulCumulCumulcumul will contain the values [1,3,6,10]. All elements of TupleTupleTupleTupletuple must be numbers (integer or floating point numbers). Each element of the result tuple CumulCumulCumulCumulcumul 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 CumulCumulCumulCumulcumul will also be an integer number.

Exception: Empty input tuple

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