In book

in section 2 it is described transition from Poisson bracket into Canonical Commutation Relations.
But it is written
The experimentally observed phenomenon of incompatible measurements suggests that position and momentum cannot be number-valued functions in QM.
What means "number-valued functions"?
I understand QM, but I do not understand this word, what he want to tell with it.
