How this random number generator works

Enter a minimum and maximum, choose how many numbers to generate, then select whether duplicates are allowed. Integer mode includes both ends of the range.

Integers, decimals and duplicates

Integer mode can generate unique values when enough numbers exist in the range. Decimal mode rounds generated values to the selected number of decimal places.

What this generator does not include

This generator is for everyday random picks. It does not claim cryptographic security, handle gambling or produce official lottery numbers.
