Notes
 Be careful using random numbers in multiplayer, each client will come up with a different result. See multiplayer tutorials for more general information about locality.
 The number returned is unlikely to be a whole number.
To return a whole number use either round, ceil or floor together with random:
x=floor(random 5) will return 0,1,2,3 or 4. (uniform distribution, all numbers have the same probability of being selected)
x=ceil(random 5) will return 0,1,2,3,4 or 5. (0 is very unlikely, but possible, as ceil 0 is 0)

 Random selections including negative numbers can be obtained via: Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)): _Xrnd = round(random 200) 100; This will yield numbers between 100 and 100.
