random numbers

[Ariel]

I Need to get a Random number from an exponential distibution.

Lets says I need a number between 1 to 100, the meanning of the exponential distribution is that

the probability of each number to get selected is diffrent.

please help.

Re: random numbers

Never heard of a Gaussian distribution? Never had decent math in school?
