Current Limits

  • Maximum input length: 100,000 characters

Choose number, integer or decimal under "Task" and set the range and count. Integers include both ends; decimals take a chosen number of digits.

When drawing several integers the same number can repeat. For no repeats, use the picker’s "pick N from a list".

What You Can Do

Integers
Draws from an inclusive range such as 1–45.
Numbers and decimals
Real-number ranges or 0–1 decimals with chosen digits.

Frequently Asked Questions (FAQ)

Is it really random?

It uses the browser’s crypto.getRandomValues rather than Math.random, and every value in the range is equally likely.
