Return the sum of all elements of a tuple.

::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.
