Set the range and output type
Choose integers or decimals, enter the smallest and largest values, and set how many results to create. Integer ranges include both endpoints. Decimal results are rounded to six decimal places when needed.
Read the result panel
The summary shows the selected range, number type, and count. The values are listed in order and the list can be scrolled when you request many results. Use Copy numbers to place one value per line on the clipboard.
Randomness and limits
The generator uses the browser randomness source when it is available and falls back to the browser’s ordinary random function. It is suitable for general number selection and examples, not for passwords, keys, tokens, or other security decisions. You can request up to 100 values at a time.
