Please be more specific: into what sort of number? Only depending on the 
sort of head or on the duration? The duration with or without dots, as 
logarithm or not? How to treat tuplets?

Here a wild guess:

%%%%%

\version "2.19.38"

\new RhythmicStaff \with {
  \override NoteHead.stencil =
  #(lambda (grob)
     (let* ((event (event-cause grob))
            (durlog (ly:duration-log (ly:event-property event 'duration)))
            (durstring (number->string (expt 2 durlog))))
       (grob-interpret-markup grob durstring)))
} {
  2. 4 4 8 16 32 32 \tuplet 3/2 { 8 8 8 } 8.. 32
}
