Hello forum,
I have a code that generates random numbers on a web form. I want to use this auto generated random numbers as reference. I studied this random numbers generated and discovered that the last 4 digits ends with 6541 for all the reference numbers.
- I want to know when random numbers are generated, will there be a repeat of numbers? I don’t want to have same reference number generated twice. If a reference number has already been generated, then it should alert the user or generate another reference.
- I also discovered that the numbers are not the same in length. Some numbers have 14 digits, while some have 13 digits. How can I make my random number have a fixed length, like 1 digits?
