Random Integers Wish - lrdheat - 04-09-2015 01:44 AM
I would like to see an option offered that would allow a user to choose between a list of random integers and a list of random numbers without duplication...equivalent to the statistical exercise of choosing balls from an urn with replacement, and an option to choose without replacement.

Good news: What you seek is already available. In the following, all parameters are assumed to be integers. RANDINT(n,a,b) --> n random integers between a and b inclusive, with possible duplicates. rand(n,a,b) --> n random integers between a and b inclusive, with no duplicates. Of course, b-a must be big enough to accommodate n items, else an error occurs. Notice that rand must be spelled in lowercase, whereas randint works in both uppercase and lowercase. Alternative method: CAS.RANDOM(n,a,b) seems to be the same as rand(n,a,b), but CAS.RANDOM must be spelled all in uppercase. RE: Random Integers Wish - lrdheat - 04-09-2015 02:36 AM
Thanks! I do remember noting this a long time ago, and forgot! This should be in the catalogue. |
