I cannot find in the description, that what is the maximum value of a seed which differs from another. And can it be zero, negative or noninteger?

"rng(seed) seeds the random number generator using the nonnegative integer seed [...]"
So the minimum difference is 1, and they cannot be negative, or non-integer, but they can be zero.
rng() passes the seed to RandStream, https://www.mathworks.com/help/matlab/ref/randstream.randstream.html
"Seed: Nonnegative scalar integer with which to initialize all streams. Seeds must be an integer between 0 and 2^32 − 1 or 'shuffle' to create a seed based on the current time. Default is 0."
