Understanding Randomness
True Randomness vs Pseudorandom
This generator uses cryptographically secure pseudorandom numbers (CSPRNG) which are computationally indistinguishable from true randomness for all practical purposes. True random number generators require specialized hardware.
Distribution Matters
Different applications require different distributions. Uniform distribution gives equal probability to all numbers, while normal distribution clusters values around the mean. Choose according to your use case.
Frequently Asked Questions
How secure are these random numbers?
Our generator uses the Web Crypto API which provides cryptographically strong randomization suitable for security applications. The implementation follows NIST SP 800-90A recommendations.
What's the maximum range allowed?
You can generate numbers between -9,007,199,254,740,992 and 9,007,199,254,740,992 (JavaScript's safe integer range). For larger numbers, consider specialized libraries.
Can I generate non-integer numbers?
This tool specifically generates integers. For floating-point numbers, generate in a large range (e.g., 1-100000) and divide by an appropriate factor (e.g., 1000).
How does the unique values option work?
When enabled, the generator ensures no duplicates appear in your results. Note that this requires the quantity to be less than the range size (max-min+1).
Are the numbers stored anywhere?
No numbers are transmitted to our servers - all generation happens in your browser. For added security, you can use this tool offline after initial page load.
