I'm not sure if we really need to limit the range of n to  0 ga'obi'iga'o 1.
According to http://www.lojban.org/tiki/BPFK+Section%3A+Numeric+selbri
we have five menbers of MOI: moi, mei, si'e, cu'o and va'e.

x1 number moi x2 x3	x1 me x2 gi'e lidne da'a number me x2 x3
x1 number mei x2	x1 me x2 gi'e klani li number lo se gradu be x2
x1 number si'e x2	x1 pagbu x2 gi'e klani li number lo se gradu be x2
x1 number cu'o x2	x1 se pacna zi'o li number va'o x2
x1 number va'e x2	x1 se merli zi'o li number x2

Besides si'e, no other menber of MOI signifies a quantity n relative
to another quantity of the same material. There is ce'i that has a
similar meaning, but it is a member of PA3 and does not form a selbri.

On this condition, it would be better not to limit the range of n for
the capability of the language. With no limit, we could say, for
example:

I vomit all I ate yesterday:
levi sanmi cu ni'upasi'e lei mi djedi cidja
(This meal is -1 times of my daily food.)

I eat too much, or I cannot eat so much:
levi sanmi cu musi'e lei mi djedi cidja
(This meal is five times of my daily food.)

On the left side of the time-dependent Schroedinger equation, the
partial derivative of the wave function psi with respect to time t is
multiplied by "i times portion of Planck constant h-bar":
le vi stodi cu ka'osi'e le la plank. stodi
(This constant is i times of h-bar.)
