# About This Calculator
A Random Number Generator (RNG) is a computational or physical device designed to generate a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance.
This tool generates Pseudo-Random Numbers using the standard algorithms built into modern web browsers. While not ensuring the same level of unpredictability as atmospheric noise or radioactive decay (True Randomness), they are perfect for everyday applications like gaming, sampling, and lucky draws.
Common Uses
- Gaming: Rolling dice, shuffling cards, or determining loot drops.
- Statistics: Random sampling from a population to avoid bias in surveys.
- Cryptography: Generating keys and salts (though cryptographically secure RNGs are preferred for high security).
- Decision Making: Flipping a digital coin to settle a debate.
How To Use
- Set the **Minimum** value (e.g., 1).
- Set the **Maximum** value (e.g., 100).
- Choose the **Quantity** of numbers to generate.
- Click **GENERATE** to see your random results.
Frequently Asked Questions
Is this truly random?+
Technically, this is a 'Pseudo-Random Number Generator' (PRNG). It uses a mathematical formula initiated by a seed (often the current time). For almost all human purposes (games, contests), it is effectively random.
Can I predict the next number?+
No. The algorithm is complex enough that without knowing the internal state of the generator, predicting the next number is impossible for a human.
Does the range include the Min and Max numbers?+
Yes! The range is inclusive. If you select 1 to 10, both 1 and 10 are possible outcomes.
Can I generate negative numbers?+
Yes, simply enter a negative number in the Minimum or Maximum fields (e.g., -50 to 50).
Why do numbers repeat?+
True randomness allows for repetition. If you roll a die twice, getting a 6 both times is perfectly normal. This tool generates numbers 'with replacement'.
Is Random Number Generator free to use?+
Yes, Random Number Generator on Matheric is completely free to use. We believe in accessible education and utility for everyone.
