As a crypto person, we generally want to be able to generate random integers that can be represented in a fixed range of bits (for example, 0 -> 1024 bits) for public/private key cryptosystems. Block ciphers and protocol nonces require the same, though usually in smaller sizes (64,128,256 bits). Generally floating point numbers are not required, as most of the algorithms operate on the natural numbers. The nice thing about obtaining a stream of bytes is that if you have one, and your Scheme system has arithmetic shift, you can get any of the above with some simple routines and a stream of random bytes.
