tuple_cumul🔗
Short description🔗
tuple_cumul — Calculate the cumulative sums of a tuple.
Signature🔗
tuple_cumul( number Tuple, out number Cumul )
Description🔗
tuple_cumul returns the different cumulative sums of the
corresponding elements of the input tuple Tuple, i.e. the i-th
element of the result tuple Cumul is the sum of the first i
elements of the input tuple Tuple. For example, if
Tuple contains the values [1,2,3,4], the output tuple
Cumul will contain the values [1,3,6,10].
All elements of Tuple
must be numbers (integer or floating point numbers). Each element
of the result tuple Cumul 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 Cumul will also be an integer number.
Exception: Empty input tuple🔗
If the input tuple is empty, the operator returns an empty tuple.
