Random Number Generator

Generate a random number within defined range.


The Random Number Generator produces random numbers within user defined range.

What is a Number?

A number is an abstract concept used to quantify or count objects or quantities. It represents a numerical value or magnitude. Numbers are used in various fields such as mathematics, science, economics, and everyday life to describe and compare quantities, perform calculations, and establish relationships between different quantities.

Numbers can be classified into different types, including natural numbers (counting numbers), whole numbers (including zero), integers (positive and negative whole numbers), rational numbers (numbers that can be expressed as a fraction), and irrational numbers (numbers that cannot be expressed as a fraction, such as the square root of 2 or π).

Numbers can be used for various purposes, such as measuring quantities (e.g., length, weight, time), indicating the position in a sequence, representing data, expressing mathematical relationships, and solving equations. They serve as a fundamental tool in mathematics and are essential for many scientific and practical applications.

Generation of randoms Numbers

Generating a random number means picking a number by chance, just like picking a toy from a bag without knowing which one you'll get. Here's how it works:

  1. First, we decide on the range of numbers we want to pick from, like from 1 to 100.
  2. Then, we start with a special number called a "seed." This seed helps us start the process of picking random numbers.
  3. Next, we use the seed to follow a special rule that helps us get different random numbers each time. It's like a secret code that helps us know which number comes next.
  4. The number we get might be between 0 and 1 at first. But if we want numbers between 1 and 100, we can change it. We make it bigger by multiplying it and adding 1. So, our number can become 1, 2, 3, and so on, up to 100.
  5. Sometimes the number might have a decimal part, like 7.5. But if we only want whole numbers, which is this tool case, we can remove the decimal part and keep the whole number, like 7.
  6. If we want more random numbers, we can repeat these steps to get as many as we need.

That's it! We use a special rule and a starting point (seed) to get random numbers within a range we choose.

Using the tool

This tool was developed for programmers and testers who have the constant need to enter different numbers in developing forms.
