Random Number Generator
Generate random numbers within any given range.
Random number generator
Choose a range and how many numbers to generate. Numbers are generated locally in your browser.
Quick ranges
Generated numbers and results
Range 1 to 100 · integer · duplicates allowed
Your random numbers will appear here.
Set a range, choose integer or decimal mode, then generate numbers locally.
Local randomization
Numbers are generated locally in your browser with no backend call.
Integer or decimal mode
Generate whole numbers or formatted decimal values.
Copy-ready output
Choose separators, sorting, and history copy options.
Dynamic Randomization Insights
Ready to generate 1 integer between 1 and 100.
Duplicates are allowed, so the same number can appear more than once.
Integer mode generates whole numbers and includes both range endpoints.
Original random order is preserved.
Use this for casual random selection, not official lotteries, gambling, or security-sensitive randomness.
How Random Number Generation Works
The generator chooses values within a selected range.
Integer mode returns whole numbers.
Decimal mode returns fractional numbers.
Duplicate settings control whether values can repeat.
Sorting changes display order after generation.
Generated values are shown in a copy-ready format.
Range, Duplicates, Integers, and Decimals Explained
Minimum and maximum define the allowed range.
Integer ranges include both endpoints.
Decimal results use the chosen precision.
Allowing duplicates means a number can appear more than once.
No-duplicate mode needs enough available unique values.
Negative ranges and zero are useful for testing and math examples.
Randomness, Fairness, and Appropriate-Use Notes
Random outputs can repeat when duplicates are allowed.
Small samples may look uneven even when random.
Browser randomization is useful for casual tools and learning.
Official contests, lotteries, gambling, and security workflows may require certified or audited randomness.
Sorting after generation changes display order only.
This tool estimates random selection for everyday use.
