## Random Number Generator

This version of the generator creates a random integer. It can deal with very large integers up to a few thousand digits.

## About Random Number Generators

There are two main types of random number generators: pseudo-random and true random.

## How to Generate Random Numbers

- What is your range? Set a minimum number and a maximum number. The random number(s) generated are selected from your range of numbers, with the min and max numbers included.
- How many numbers? Specify how many random numbers to generate.
- Allow repeats? If you choose No your random numbers will be unique and there is no chance of getting a duplicate number. If you choose Yes the random number generator may produce a duplicate number in your set of numbers.
- Sort numbers? You can decide not to sort your random numbers. You can also order your random numbers ascending, lowest to highest or descending, highest to lowest.

## Example: Generate a Random Number to Use as a PIN .

To generate a 6-digit PIN with or without duplicate digits choose the following settings:

Do it: Generate a 6 digit PIN without duplicates

## Example: Randomize a Set of Numbers

Choose the following settings to randomize order of selection:

Do it: Randomize the order of a set of numbers, 1 to 10

## Example: Randomly Choose One Number From a Range of Numbers

Say you want randomly select one number from 1 to 10, like drawing a number out of a hat.

Choose the following settings:

Do it: Random number generator 1 to 10

Also try: Random number generator 1 to 100

## Example: Lottery Number Generator

Choose the following settings in the random number generator:

Do it: Generate 5 lottery numbers from a range of 1 to 49

## Random Integer Generator

## Part 1: The Integers

Generate random integers (maximum 10,000).

Each integer should have a value between and (both inclusive; limits ±1,000,000,000).

## Part 2: Go!

Be patient! It may take a little while to generate your numbers...

A pseudo-random number generator is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. Computer based random number generators are almost always pseudo-random number generators. Yet, the numbers generated by pseudo-random number generators are not truly random.

Random Integer Generator This form allows you to generate random integers. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. Part 1: The Integers Generate random integers (maximum 10,000).
