Random Number Generator
What is a Random Number Generator?
A Random Number Generator (RNG) is a calculator tool that produces random numbers without any predictable pattern. It can instantly generate numbers within a specific range (e.g., 1–100) or a single random number. RNGs are widely used in gaming, lotteries, statistics, and cryptography.
How Does a Random Number Generator Work?
A random number generator works by applying algorithms that ensure unpredictability. Some generators are pseudo-random (based on formulas), while others use true randomness (based on natural events like radioactive decay or atmospheric noise).
A pseudo-random generator is more than enough for most daily uses—like picking winners, rolling virtual dice, or shuffling lists.

It eliminates bias in games, lotteries, and competitions.
Convenience
