(** The two following functors summarize all known facts about N.

    - [ZBasicProp] provides properties of basic functions:
      + - * min max <= <

    - [ZExtraProp] provides properties of advanced functions:
      pow, sqrt, log2, div, gcd, and bitwise functions.

    If necessary, the earlier all-in-one functor [ZProp]
    could be re-obtained via [ZBasicProp <+ ZExtraProp] *)
