Random Number Generator

Generate random numbers within a custom range. Perfect for games, lotteries, random selections, and testing.

Key Terms

• Random Number: Unpredictable number generated by algorithm
• Range: Minimum and maximum boundaries (min-max)
• Pseudorandom: Computer-generated randomness (appears random but algorithmic)
• Seed: Starting value for random generation (not used here)
• Multiple Generation: Creating many random numbers at once

What Are These Terms?

Random Number

A number generated without predictable pattern. Computers use algorithms to create "pseudorandom" numbers that appear random for practical purposes.

Range

The minimum and maximum values define your range. For example, range 1-100 can generate any whole number between 1 and 100 (inclusive).

Multiple Generation

Instead of generating one number at a time, you can create multiple random numbers in one click - useful for lottery picks, team assignments, or A/B testing.

How Does The Tool Work?

Generation Method

Uses JavaScript's Math.random() algorithm:

• Generates decimal between 0 and 1
• Scales to your min-max range
• Rounds to whole number
• Repeats for count you specify

Real-World Examples

Example 1: Dice Roll

• Min: 1, Max: 6, Count: 1
• Result: 4
• Perfect for board games

Example 2: Lottery Numbers

• Min: 1, Max: 49, Count: 6
• Result: 7, 23, 31, 42, 15, 38
• Generate lottery ticket numbers

Example 3: Random Selection

• Min: 1, Max: 100, Count: 10
• Result: 45, 12, 89, 67, 3, 91, 28, 54, 76, 19
• Select 10 random participants from 100

Common Use Cases

• Dice games and simulations
