Hmmm. This is only about terminology, and I'll have to stick with
mine in this case. There are "real" random generators, but that term is
usually
reserved for analog devices which output a voltage signal. Quite
popular in
white noise generators. As for the number model you are quite correct
that there is a major difference between real numbers and floating-point
numbers. It is just that I was talking about RNGs not numbers.
