About this tool
Both endpoints are inclusive — a range of 1 to 100 can produce either 1 or 100. "Allow duplicates" off draws without replacement (like pulling numbered balls from a bag, each value can appear at most once), which naturally caps how many numbers you can request to the size of the range; with decimals allowed, "no duplicates" is turned off automatically, since real numbers in a range are effectively never exactly equal.
Nothing generated here is sent to a server — the entire tool runs as JavaScript in your browser tab.
