Thanks. This indeed looks improved in several ways.

Norm function is better idea - might also be user defined version for user
defined type.

 I may get some time to try some other refinements and experiments. (Would
several zeros be better casted to type T in case T is a user defined type (an
interval type perhaps?)?)

Testing on NIST test data (tricky) is also a must. We mustn't follow Excel -
and get the wrong answer!
