Default Random Function in UDF per DPM
Posts: n/a
Hi users, I need to generate an array of random part_id #. I tried to use c function 'rand()%scalefactor' and 'srand(time(NULL))' but I need number between 1:10,000,000 and rand() returns numbers bw 0:37,***. How doing? THANKS a lot! Adriano

If rand() returns real numbers then you would just have to boost them to the size you want, i.e.

your_random_number = rand() * (10000000.0 / 37.0);
