How to Use This Calculator
- Set the minimum and maximum values to define your desired range
- Specify how many random numbers you want to generate (1-10,000)
- Choose the number of decimal places: 0 for integers, or 1-10 for decimal numbers
- Check or uncheck 'Allow duplicates' based on whether you want unique numbers only
- Click Generate to create your random numbers, which will display with sum and average statistics
Formula
Random number = Min + Random() × (Max - Min). For integers, use Math.floor(). For decimals, round to specified precision using toFixed().
Frequently Asked Questions
Are these numbers truly random?▼
These are pseudo-random numbers generated by JavaScript's Math.random() function. They're suitable for most purposes but not cryptographically secure. For security-sensitive applications, use crypto.getRandomValues().
What does 'allow duplicates' mean?▼
When enabled, the same number can appear multiple times in the results. When disabled, each generated number will be unique (if the range allows enough unique values).
How many decimal places can I use?▼
You can specify 0-10 decimal places. 0 decimal places generates integers, while higher values generate floating-point numbers with the specified precision.
What's the maximum count I can generate?▼
You can generate up to 10,000 random numbers at once. For larger datasets, consider running the generator multiple times.
