Operator Reference
tuple_sum (Operator)
tuple_sum — Return the sum of all elements of a tuple.
Signature
Description
tuple_sum returns the sum of all elements
of the input tuple Tuple. All elements of Tuple
either have to be strings or numbers (integer or floating point numbers).
It is not allowed to mix strings with numerical values. The result
parameter Sum will contain a floating point number, if
at least one element of Tuple is a floating point number.
If all elements of Tuple are integer numbers the resulting
sum will also be an integer number. If Tuple contains strings,
the concatenation will be used for building the sum.
Exception: Empty input tuple
If the input tuple is empty, the operator returns an empty tuple.
