−  x=round(random 5) will return 0,1,2,3,4 or 5.  +  x=round(random 5) will return 0,1,2,3,4 or 5. (nonuniform distribution, 0 and 5 are half as likely to be selected than any of the other numbers) 
−  x=floor(random 5) will return 0,1,2,3 or 4.  +  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)  +  x=ceil(random 5) will return 0,1,2,3,4 or 5. (0 is very unlikely, but possible, as ceil 0 is 0)

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:
