Code:
mob/verb/test()
    var
        zero = 0
        one = 0
    for(var/i = 0; i < 1000000; i++)
        if(rand(-0.05,0.05))
            one++
        else
            zero++
    world << "0's : [zero]"
    world << "1's : [one]"


Problem description:
It seems rand(-0.05,0.05) returns 0 either 1; with probability of 9:1:
0's : 909661
1's : 90339

Is this a bug, or intended functionality?

rand() only returns integers, so these results are simply a matter of DM's rounding I would imagine.
