This customizable random number generator is powerful and free. It lets you set minimum and maximum values for the created number, it also lets you customize many options including how many random numbers are produced. Want to generate multiple numbers between -10 and +200? Go ahead. Yes, you can generate random negative numbers as well.
If you want to generate multiple random numbers to simulate many throws of a dice for example, you can do it with numbers between 1 and 6. Or maybe you want to generate 7 random numbers between 1 and 49 to simulate a lottery pick, that's easy to do as well.
Another powerful feature of this random number generator is the ability to include decimal places. Simply select from the drop down how many decimal points you want included, 0 is the default. You can produce random numbers between -0.5 and 1.5 for example.
Ultimately random numbers can be very useful for a huge variety of purposes, whether it's educational, entertainment, financial, raffle draws, lottery picks, etc. The need for a random number generator that can be customized to your many needs is important.
You can customize this random number generator to display the results in a variety of ways. Including in sets of numbers, with spaces, commas, spaces and commas, or put every result on a new line. You can also sort the numbers from highest to low, and lowest to high (descending and ascending order)
If you select Cryptographic Random as your number generating engine, the numbers produced are cryptographically strong. This means the numbers produced are based on the same engine and algorithms that produce random numbers for cryptographic purposes (encryption, decryption). Cryptography is important for financial institutions, order processing, online security, government, etc. One potential drawback is the number generation may be slower when generating large quantities of numbers compared to the pseudo random option.
The Pseudo Random engine option means the random number generator will produce random numbers based off of algorithms that are technically random, and meet the definition of random, but use definitive algorithms. This means they would not be ideal for cryptographic purposes. They may however be generated a bit faster when you use the random number generator to produce large quantities of numbers.
What about true randomness you may ask? Well true random numbers are themselves still theoretical in nature. All random numbers require a certain "seed" value that is put into a complex algorithm that randomizes that value. The more random the seed value the better. However, even the universe has uniformity. Atoms may seem random in nature, but then why does the earth hold together? Or our bodies don't explode? Why does the earth travel in such a uniform pattern around the sun. Believers of true random numbers are by default proponents of the oh-so fallible chaos theory. Or something like that.
