tuple_less — Test whether a tuple is less than another tuple.
tuple_less tests whether the input tuple T1 is less than T2. A tuple T1 is said to be less than a tuple T2, if T1 has been found to be less when comparing it elementwise to T2 or (for the case that the elementwise comparison did not show that T1 is less than T2) if T1 has got less elements than T2. With the elementwise comparison the single elements of T1 and T2 are compared with each other one after another (i.e., the first element of T1 is compared to the first element of T2 and the second element of T1 is compared to the second element of T2 etc.). If an element of T1 is less than its counterpart of T2, T1 is said to be less than T2. As a precondition for comparing the tuples elementwise two corresponding elements must either both be (integer or floating point) numbers or both be strings. Otherwise tuple_less returns an error.
