Random Number Generator

Tool Introduction

This tool is an online random number generator that can quickly generate a sequence of random numbers that meets the requirements according to the user's set starting number, ending number, number of generations, and other parameters. It supports deduplication, sorting, and custom output formats to meet the needs of different scenarios.

How to Use

1. Set the number range: Enter the required numerical range in the "Starting Number" and "Ending Number" columns.
2. Set the number of generations: Enter the number of random numbers to be generated in the "Number of Generation" column.
3. Deduplication settings: If you need to generate non-repeating random numbers, check the "Deduplication" checkbox.
4. Sorting method settings: Select an option in the "Sorting Method" drop-down menu, you can choose "Random Sorting", "Ascending Order" or "Descending Order".
5. Output format settings: Select an option in the "Output Format" drop-down menu, you can choose "Plain Text", "Group Display" or "One Per Line".
6. Group size settings (only effective when "Group Display" is selected): Enter the number of digits to display per group in the "Group Size" column.
7. Number padding settings: If you need to pad the numbers with zeros, check the "Number Padding" checkbox and enter the length of the number after padding in the "Padding Length" column.
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 non-repeating random numbers between 1-10, sorted in ascending order, plain text output:
  • Starting Number: 1
  • Ending Number: 10
  • Number of Generation: 5
  • Deduplication: Check
  • Sorting Method: Ascending Order
  • Output Format: Plain Text

   

Common Problems

• Q: What input formats are supported?
•  A: The starting number, ending number, and number of generations must be integers. The group size and padding length must also be integers.
• Q: What is the format of the output result?
•  A: The output result can be plain text (numbers separated by commas), group display (numbers are displayed in groups of the specified size, with line breaks between groups), or one per line (each number occupies a separate line).
• Q: Are there any usage restrictions?
•  A: Due to browser performance limitations, generating too many numbers may cause the page to freeze. It is recommended to adjust the number of generations according to the actual situation. The starting number must be less than the ending number.

Precautions

• Please ensure that the entered number range is reasonable to avoid generating a number of generations that exceeds the range, resulting in program errors.
• If the "Deduplication" option is checked, but the number of generations is greater than the number range, the final number of generated numbers will be less than the set number of generations.
• When using the padding function, you need to ensure that the padding length is sufficient, otherwise it may cause the numbers to be displayed incompletely. For example, to generate numbers from 1-1000, the padding length needs to be at least 3.
