In practice it's probably somewhat bigger than 1 ULP. A typical PRNG will first generate a 32-bit integer and then map it to a float, giving a resolution coarser than the 52 bits of an IEEE double. But even then, the probability of getting exactly 0.5 is only 1/2^32, which you're not likely to notice. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
