We were /random for a item..

I did /random 1000 by a mistake and got 871.

Would anyone think it could not be shortened down to 87.1?

Ie. i did /random 100 and got 87..?

Cheers

so if i get 872 i would have beaten u bbut it gets rolled down to 87 so we both random again since its a draw? :eek7:

just say oops and random 100 imo :clap:

well you have a higher chance of rolling high on /1000 then on /100 if you want to turn it down to 87.1 so not fair really

eeeeeeeeeeeeeeeerrrrrrrrrrrrrrrr, no?

to poster, i guess you could but shouldnt really. clear rules is always best :p

ot: i did /random 100 by mistake on phoenix loot and got 100. rerolled /random 1000 and got 300, just my luck to waste my luck on the mistype. :)

Someone PLEASE give him a maths lesson... did u miss the class on probabilities? :D

well tbh computer random numbers are not random in slightest mean. Most of random algorithms are just complex equotation taking current computer time as a parameter. And yes, it is also able to cheat this random generator a bit to get more of what you need (I spend few sleepless days to verify this theory and it really works)... BUT only in case you have 24 hours to do so.
In fact, random numbers generator gives you number in range <0;1> (double precission) that is multiplied by parameter of /random command and printed as rounded integer value (ie.. generator gives you 0.4358686748425858... and you type /random 1000.. resulting in 435 or 436 depending on rounding/truncating of the rest of decadic development)... So, if you did /random 100 instead of /random 1000 at exactly same time, you would get exactly same number (just 10 times smaller).

Alas for sake of good manners, do correct your /random to the raid leader rules.

As for equal probability to get same ammount of every possible /random x results... for most of random numbers generators it works that if tested for very large scale (10^9 attempts +), you'll get very very slightly more low-end numbers than high-end ones (less than 0,0001% difference between the most frequent and the less frequent result).

So, it is really nothing to worry about unless you need very precise scientific calculations. If so, you need much better random numbers generator (MatLab or Mathematica 4tw).

I have no doubt DAoC server uses just classic simple random numbers generator - two reasons: 1. It is random more than enough for game needs and 2. It doesn't consume too much CPU time.

I know how a random generator works... but arent u agreeing with me, that the probability of rolling a high number on /random 100 is the same as for /random 1000? or was this just the math lesson for hamro? hehe :D

Ye, long story short, it's exactly the same ;-)

It usually takes longer to type "/random 1000" then "/random 100" so your request would most likely have illicited a different result from the server. Net results is that you can't just rescale the roll because you got it wrong.

apologise. reroll correctly. live with it.
