Random Number Generator

Tool Introduction

This tool is an online random number generator that can quickly generate random number sequences according to user-defined parameters such as starting number, ending number, and quantity to generate. It supports uniqueness, sorting, and custom output formats to meet the needs of different scenarios.

How to Use

1. Set Number Range: Enter the desired numerical range in the "Starting Number" and "Ending Number" fields.
2. Set Quantity to Generate: Enter the number of random numbers to generate in the "Quantity to Generate" field.
3. Uniqueness Setting: If you need to generate non-repeating random numbers, check the "Unique" checkbox.
4. Sort Order Setting: Select an option from the "Sort Order" dropdown menu. You can choose "Random Order", "Ascending Order", or "Descending Order".
5. Output Format Setting: Select an option from the "Output Format" dropdown menu. You can choose "Plain Text", "Grouped Display", or "One Per Line".
6. Group Size Setting (only effective for "Grouped Display"): Enter the number of digits to display per group in the "Group Size" field.
7. Number Padding Setting: If you need to pad numbers with zeros, check the "Pad Numbers with Zeros" checkbox and enter the desired length for the padded numbers in the "Padding Length" field.
8. Click the "Generate" button to view the generated random numbers in the text box below.

Usage Examples

Here are some usage examples:

• Example 1: Generate 5 unique random numbers between 1-10, sorted in ascending order, plain text output:
  • Starting Number: 1
  • Ending Number: 10
  • Quantity to Generate: 5
  • Unique: Checked
  • Sort Order: Ascending Order
  • Output Format: Plain Text

   

Frequently Asked Questions

• Q: What input formats are supported?
•  A: Starting number, ending number, and quantity to generate must all be integers. Group size and padding length must also be integers.
• Q: What is the output format?
•  A: The output can be plain text (numbers separated by commas), grouped display (numbers displayed in groups of a specified size, with newlines between groups), or one per line (each number on a separate line).
• Q: Are there any usage restrictions?
•  A: Due to browser performance limitations, generating a very large quantity may cause the page to freeze. It is recommended to adjust the quantity to generate according to actual circumstances. The starting number must be less than the ending number.

Notes

• Please ensure that the entered number range is reasonable to avoid generating quantities outside the range, which could lead to program errors.
• If the "Unique" option is checked, but the quantity to generate is greater than the number range, the final number of generated digits will be less than the set quantity to generate.
• When using the padding function, ensure that the padding length is sufficient, otherwise, the numbers may not be fully displayed. For example, to generate numbers from 1-1000, the padding length needs to be at least 3.
