What is Random Number Generator

This Random Number Generator can generate one or more random numbers in your custom range from 0 to unlimited. Generate positive random numbers with repeats or no repeats.

What are the types of random number generators

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

pseudo-random number generator (PRNG) is typically programmed using a randomizing math function to select a "random" number within a set range. These random number generators are pseudo-random because the computer program or algorithm may have unintended selection bias. In other words, randomness from a computer program is not necessarily an organic, truly random event.

A true random number generator (TRNG) relies on randomness from a physical event that is external to the computer and its operating system. Examples of such events are blips in atmospheric noise, or points at which a radioactive material decays. A true random number generator receives information from these types of unpredictable events to produce a truly random number.

This calculator uses a randomizing computer program to produce random numbers, so it is a pseudo-random number generator.

How to use this calculator 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.
