[R] Drawing random numbers from Uniform distribution with infinite range

[Richard O'Keefe]

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?
