    initial v19

    1515Problem seems to be that in `M.n??` we see that it's looking for `is_a_numeric(x._gobj)` but apparently that fails, as does the constant, so it thinks we are looking at evaluating `sgn(cos(x))` instead of `sgn(cos(3/2))`.

     17UPDATE:
     18The problem also appears with `polylog(2.,.9).n()` for example.
