[math-fun] refining the notion of density

Rich S. asks:

Are you using Conway Numbers as density values?

No; my density "values" are a different sort of thing; more along the lines of elements of the ordered ting |R[epsilon] where epsilon is a formal indeterminate satisfying epsilon < r for all r > 0 in |R. Or at least, that's what I _think_ they're like. My values come from a somewhat abstract modding-out construction so I don't have a concrete picture of what they look like in general. Jim Propp
