The (highest) multiplicity of the beam. So 0 (=0 beams) is not used.

A stem is considered to be in forced direction, in every case when
it happens to point in an unnatural direction (eg, all upward stems
of notes that are above central staff line).

Yes. The naming and use of vertical units of length are a big mess.
