Random Number Maker is a random number generation tool that allows you to easily generate random numbers by simply inputting the number of numbers to be generated, the minimum value, and the maximum value. It can generate up to 1000 random integer numbers and download them in text or CSV format.

How to use

  1. Enter the "Random number range (minimum value)", "Random number range (maximum value)", "Number of outputs (within 1000)", and "Allow duplicates".
  2. The "Random number" will be displayed automatically.
  3. Click the button on the top right to "Copy", "Download text file", or "Download CSV file".

What is a random number?

Random numbers are a set of numbers that have no specific rules or patterns and cannot be predicted. In the fields of computers and mathematics, random numbers are defined and used as follows:

Characteristics

Unpredictability

  • Random numbers are numbers that do not follow any particular pattern or predictability.
  • Example: The outcome is not known in advance, like the number you get when you roll a dice.

Range constraints

  • Random numbers are usually set to a range of values ​​that are generated.
  • Example: Random numbers generated within the range of 1 to 6.

Uniformity

  • A truly random number requires that each value is generated with the same probability.
  • Example: In the range of 1 to 6, the probability of each number appearing is 1/6.

Types

True Random Numbers

    Random numbers generated using real-world physical phenomena (such as noise and radioactive decay). Completely random and unrepeatable.

Pseudo Random Numbers

  • Random numbers generated computationally using an algorithm.
  • Repeatable (the same sequence of random numbers can be generated using the same initial values).
  • Commonly used in computers.

Uses

  • EncryptionRandom numbers are used to generate cryptographic keys for security.
  • SimulationRandom numbers are used in weather forecasts and random events in games.
  • StatisticsRandom sampling of data.
  • GameUsed to generate random events such as enemy behavior and the contents of treasure chests.
  • Machine LearningUse random numbers to shuffle data and initialize models.
