Random Number Generator — Integers & Decimals (Inclusive)

Pick a random integer or decimal in a custom range. Inclusive bounds, precision control, optional bulk output. Private by design.

Range & Options

Bounds are inclusive after rounding to your chosen decimal places.

About the Random Number Generator

This tool allows you to generate random numbers based on your specific needs. You can define the minimum and maximum values for the range and specify the number of decimal places for the generated number.

How it Works

The Random Number Generator operates entirely client-side within your browser using JavaScript's built-in Math.random() function. This ensures your privacy as no data is sent to a server.

  • Minimum Value: The smallest possible number that can be generated.
  • Maximum Value: The largest possible number that can be generated.
  • Decimal Places: Controls the precision of the generated number. A value of 0 will result in an integer.

Key Features:

  • Customizable Range: Set your desired minimum and maximum values.
  • Precision Control: Specify the exact number of decimal places for the output.
  • Client-Side Operation: All calculations are performed in your browser, ensuring privacy.
  • Simple Interface: Easy to use with clear input fields and a single "Generate" button.

FAQs

Are the bounds inclusive?

Yes. Results are returned within the inclusive range [min, max] after rounding.

Can I generate integers only?

Absolutely—set decimal places to 0.

Is this cryptographically secure?

No. Math.random() is not suitable for cryptographic or security-critical needs. Use a cryptographically secure RNG for those scenarios.

Can I repeat results or generate multiple numbers?

This page outputs a single number per click. If you need multiple numbers, non-repeating lists, or seeding, consider creating a dedicated “Bulk RNG” tool or export feature.
