Random Number Generator

Eon CalculatorThe random number generator is a process that generates a series of random numbers that cannot be predicted more accurately than by chance. These random numbers are more frequently used in a variety of industries from cryptography to gaming. Keep reading to learn more about what is the random numbers are, types of random numbers, and how to generate random numbers.
What is a random number?
A random number is a numerical value selected from a set of possible values where each value has an equal probability of being chosen. In essence, a random number is one that emerges without any discernible pattern, logic, or predictability. Such numbers are crucial when fairness, unbiased outcomes, or pure chance are required.
There are two primary categories of random numbers based on their generation method: True Random Numbers (TRNG) and Pseudo-Random Numbers (PRNG).
There are two primary categories of random numbers based on their generation method: True Random Numbers (TRNG) and Pseudo-Random Numbers (PRNG).
True Random Numbers:
These random numbers are made by physical processes that are not predictable. The numbers come from naturally random events in the world, like Noise caused by heat in electrical lines, noise in the air, decay of radioactive materials and how photons behave (quantum physics). These numbers are truly random because the source is real and can't be predicted.
Pseudo-Random Numbers:
Pseudo-random numbers are generated using algorithms that simulate randomness. Although the output appears random, it is deterministic because it is produced by a formula and an initial value called a seed. If the same seed is used, the sequence of numbers will always be identical. PRNGs are suitable for most applications, including games, simulations, and general computing.
PRNG Formula & Explanation
Pseudo-random numbers are made by algorithms that simulate randomness. The output looks random but it is actually made with a formula and an initial number called a seed. If you start with the same seed, the sequence of numbers will always be the same. Pseudo-random numbers are good for most situations, like games, simulations, and general-purpose computing.
How to Use This Generator
Using our random number generator is straightforward. Whether you need one number or multiple numbers, our tool is designed to make the process efficient. Below, we explain how to use this generator step-by-step along with examples.
- Step 1: Enter the minimum value, this is the smallest number you want to include in your range. Example: if you want a number between 5 and 50, your minimum value would be 5.
- Step 2: Enter the maximum value, this is the largest number you want to generate. Example: For a range of 5 to 50, the maximum value would be 50.
- Step 3: Specify how many random numbers you need to generate. For example: if you need 10 random numbers between 5 to 50, set the quantity to 10.
- Step 4: Press the generate button to instantly create your random numbers. You can easily copy the generated numbers to your clipboard.
This generator is an essential tool for several applications, from creating secure passwords to generating random lottery numbers. The generator's settings can be modified to generate output that is customized to your specific needs.
| Task | Min | Max | Quantity | Repeats | Sort |
|---|---|---|---|---|---|
6-digit PIN | 0 | 9 | 6 | Yes or No | Do not sort |
Lottery | 1 | 49 | 6 | No | Optional |
10-digit PIN | 0 | 9 | 10 | Yes | Do not sort |
Random team | 1 | 20 | 20 | No | Do not sort |
4-digit OTP | 0 | 9 | 4 | Yes | Do not sort |
Dice roll | 1 | 6 | 1 | N/A | N/A |
Table 1 shows a summary of settings for common tasks.
Create a 6-Digit PIN
A 6-digit PIN is commonly used for secure access to systems, accounts, computers, and mobile devices. Here are the settings to use: Min = 0, Max = 9, Generate = 6 numbers, Allow repeats = Yes (if duplicates are acceptable) or No (if you need unique digits), and Sort numbers = Do not sort.
Create Lottery Numbers
Lottery games typically require random number selection within a defined range. This tool helps you quickly select your lottery numbers. Use the following settings: Min = 1, Max = 49, Generate = 6 numbers, Allow repeats = No (because each lottery number must be unique), and Sort numbers = Sort in ascending order (optional for easier reading).
Randomly Assign Teams
This tool is ideal for dividing participants into teams for games, challenges, or group activities. Use these settings: Min = 1, Max = 20, Generate = 20 numbers (to cover all participants), Allow repeats = No (you want each participant to be assigned only once), and Sort numbers = Do not sort (to maintain the original random order).
Pick a Random Number
This tool can simulate games and activities such as rolling a dice or choosing a winner in a contest. Use the following settings: Min = 1, Max = 6 (for a six-sided dice), Generate = 1 number, Allow repeats = No, and Sort numbers = No.
