Your posts, while articulate, seem to be veering off into meta-land.
If your original question was:
What is the difference between
1r3
and
111r333
. . .
When in the forth or fifth grade my teacher was trying to explain the
difference between pencil leads "2 1/2" verses those rated at "2.5". It
went something like this: Pencils with a lead of "2 1/2" meant that the
hardness was somewhere between "2 1/4" and "2 3/4", where a hardness of
"2.5" meant it was between "2.45" and "2.55". I seem to remember seeing
some pencils with a hardness of "2 2/4" also. I couldn't tell any
difference on how the pencils worked.
I remember something about a convention which has been lost with the
advent of computers of writing a number, say "2.5" implied that the
measurement was good to a tenth, where "2.500" implied it was good to a
thousant.
