I can't see anywhere you can get a divide by zero error in this script,
unless there is a bug in the random function. But I suspect there is an
easier way to do this:
function myRandom lower,upper
return trunc((random(30000)-1)/30000 * (upper - lower)) + lower
-- returns a whole number R, lower <= R < upper
end myRandom
30000 isn't a particularly special number, I just pick it because it is
large, thus giving myRandom a fairly high resolution.
If you need to include both bounds in the range of values, use
random(30000) instead of random(30000)-1.
