Random Number Generator

Set “From” and “To” and click “Generate new”: by default you get one whole number from 1 to 100, both ends included. Set “How many” up to 10,000 to draw a whole list, and tick “No repeats” when each number may come only once, as in a lottery or a raffle. If the range has fewer different numbers than you asked for, the generator shows all of them in random order and tells you so. “Decimal places” gives decimals with up to 10 digits after the point, and negative numbers work too. Under “Order” keep the numbers as drawn or sort them, and choose a “Separator”: a new line, a comma or a space.

Each number is drawn with the cryptographic random generator of your browser, by a method that gives every number of the range exactly the same chance, so there are no favourite numbers and no hidden rules. Very large ranges work as well. Under the list you see how many numbers were drawn and their sum. Use the generator to pick the winner of a giveaway by the numbers of the participants, to roll dice for a board game, to draw lottery numbers, to choose a random page or question, or to make test data, then copy or download the list.
