The uniform distribution with infinite range gives each possible answer infinitesimal probability of being chosen. In the standard real numbers, that probability is ZERO. In fact, the probability of getting a number in *any* prespecified finite range is the same, ZERO. One such finite range is the numbers that can be represented in floating-point. So you are with certainty not going to draw a representable number. A complete answer to your question is thus ifelse(runif(N) < 0.5, 1, -1)/0
Why do you think you need this?
