Thread: Prelude's random numbers tutorial

> But you should look the code above again to see if you really understood what the probability is for all possible results. I think you will find that all results have a 1 / (RAND_MAX + 1) probability. Not just 10.

Code:

std::rand() * 9.0 / RAND_MAX + 1;

Is that the piece of code you were talking about?

There's a world of difference between

Code:

std::rand() * 9.0 / RAND_MAX + 1

and

Code:

std::rand() * 9.0 / (RAND_MAX  + 1)

Only your second code snippet that involved a bucket_size works as expected.

can u post a code that will make a random int and store it to x
the random int are so confusing
