How does the random number generator work?
Our random number generator uses JavaScript's Math.random()
function, which generates pseudo-random numbers using a
sophisticated algorithm. While not truly random (they're generated
by a deterministic algorithm), they're sufficiently random for most
practical purposes like games, simulations, and random selection.
What is the range of numbers I can generate?
You can generate numbers within a very wide range. The minimum value
can be as low as -1,000,000,000 and the maximum as high as
1,000,000,000. However, for very large ranges, the distribution
might not be perfectly uniform due to JavaScript's number precision
limitations.
Can I generate multiple random numbers at once?
Yes! Use the "How many numbers to generate?" field to specify how
many random numbers you want. You can generate up to 100 numbers at
once. Each number is generated independently within your specified
range.
Are the numbers truly random?
The numbers are pseudo-random, meaning they're generated by a
mathematical algorithm rather than from a physical random source.
For most applications (games, simulations, random selection),
they're random enough. For cryptographic or security purposes, you
would need a cryptographically secure random number generator.
What are some practical uses for this tool?
This tool has many practical applications:
• Games: Dice rolls, card games, random events
• Education: Probability experiments, math exercises
• Decision Making: Random selection, tie-breaking
• Testing: Generating test data, simulations
• Lotteries: Creating random number combinations
• Research: Random sampling, statistical analysis
