The problems in that code are that you're using completely the wrong types.

In key_t, you're inheriting the base_type copy-constructor and 
copy-assignment, and then creating new shadowing constructors and 
assignment operators for the base_type (note: these are *not* a 
copy-constructor nor copy-assignment operator for key_t itself!).

In numeric_t(const sign_type& other), you're getting compile errors 
because you probably intended to use numeric_t instead of sign_type as 
the parameter.
