Frequently Asked Questions
What does random number list with no repeats mean?
It means the calculator returns multiple integers where each integer can appear at most once in the list. The list is sampled without replacement from the allowed integers in the interval.
How does interval type affect which integers can appear in the list?
The interval type determines whether min and max are included. For example, [min, max] allows both endpoints, while (min, max) excludes both endpoints so only integers strictly between them can be drawn.
Why does the calculator say there are not enough integers in the interval?
This happens when the number you request is larger than the count of distinct integers available under the chosen interval rules. Increase the range, include endpoints, or request fewer integers.
What is the difference between keeping random draw order and sorting ascending?
Keeping random draw order shows the integers in the order they were selected. Sorting ascending rearranges the same selected integers from smallest to largest without changing which integers were drawn.
