Dear Community, I want to generate x random numbers and compute some descripive statistics on the results. Than I round the values of the random numbers and want to know, how my desriptive statistics have changed. I want to make this process n times. I have two questions. 1. Is there a way to set the roundings Base, I mean to the nearest 0,1 or 10. Not just integers but other rounding rules I mean. 2. Why can't I store my results to the xxx.gdt using the store command? I get the message: 'a' is not the name of a variable I know a is a scalar, but how do I store it than? Thanks for your help, and if you know any papers/articles on this topic, please let me know! Have a nice day!
