Generate random whole numbers in a custom range

Enter the minimum and maximum as ASCII integers from −1000000000 to 1000000000, inclusive. The minimum cannot exceed the maximum; negative ranges and equal bounds are valid. Decimal and scientific/exponential notation are rejected. The count must be a whole number from 1 to 100. Each result appears on its own line and numbers may repeat; this is not a unique selection. A one-number range always returns that number: range 7–7 with count 3 gives three lines of 7. Results in wider ranges may vary between generations. Unlike the fixed coin and dice options, this tool accepts a custom range including negative values. It uses the browser’s Web Crypto getRandomValues source; rejection sampling avoids modulo bias when mapping values into the range. Generation is local and makes no requests to an external random-number service. Defaults are range 1–100 and count 10. Copy the result, or use Clear to restore defaults and remove output. Entered bounds and results are not sent to a server.
